baseball bat sweet spot physics

But man, hit it right on the sweet spot and it feels like you are a baseball god. If the ball is also mounted as a pendulum, the experiment can also be performed in reverse, by swinging the bat at a stationary ball. >> It is almost as easy as walking. Aluminum tubes are 24 to 35 inches (61 to 89 centimeters) long and 2 to 3 inches (5 to 7.6 centimeters) in diameter for making an aluminum bat. If you turn the volume up you will hear how the swing speed affects the sound of the swish through the air. , 231-232 (2001). >> At the major league level, maple bats now account for 75% to 80% of all bats. The faster the hit ball travels, the longer it should travel. So, if you make sure the label is up, it means that you will be making contact with the edge of the grain which is the strongest part. An impact at the fundamental node will not excite that mode, but it will excite the second mode. A careful analysis of baseball dynamics shows that this special spot is located at the point where an applied force would result in pure rotation of the bat about the handle grip. A baseball bat is typically between 30-34 inches in length and can weigh anywhere from 24-30 ounces. He has been writing about the sport for over five years and is passionate about sharing his knowledge and enthusiasm for the game. Except, of course, when you hit the sweet spot. There is a significant difference between end-load and balanced softball bats in terms of weight distribution. << /Gamma [1.8 1.8 1.8] Baseball is based on the principles of Newtons laws of motion. When To Know Its Time To Replace Your Baseball Mitt, Customizing Your Baseball Bag: A Guide To Personalizing Your Equipment. The technique here can be be used to measure the performance of any bat, at least at low ball speeds. When a ball is hit in the sweet spot, the collision of the bat and ball creates a compression wave which travels through the bat and is then transferred to the ball, causing it to travel further. A similar result is obtained when swinging cylindrical rods, as described in a paper that can be downloaded here. Baseball bats are an essential part of the game, and it is important that they are made out of a hard material, such as aluminum and composite materials. Two ounces doesnt seem like much but Ive seen it make a large difference. The cookie is used to store the user consent for the cookies in the category "Performance". It's where the wood grain is strongest. Maple and ash are the most commonly used materials in major league baseball. From that you can work out the speed and spin of the ball before and after it bounces. If the ball is at rest (when striking a ball off a T ) then. Theres one where it feels good in your hands, one where the ball comes off the fastest. /N 7 0 R Its center of mass is 52.6 cm from the knob end. q is also called the apparent coefficient of restitution or ACOR. The node is related to where the sweet spot is - where the bat does NOT bend or vibrate. QuickTime movie files A and B show a baseball bouncing on a block of granite. Elastic behaviour in the vertical direction is described by a number called the coefficient of restitution (COR) which is about 0.5 for a baseball, depending on ball speed. << Each type of wood has its own unique characteristics, making it important for players to consider the type of wood when selecting a bat. % MLB . There is enough physics in it to keep a PhD student busy for a few years, but it could also be done by any high school student as a simple introduction to the physics of baseball. /R [316 73 572 791 ] << The sound made by a bat can be described as a "ping". The Sweet Science. } Since the CM traces out a spiral rather than a circular path, the center of the circle moves, as the bat is swung, along the path traced out by the inner circle of black dots. For the purposes of this paper, I will attempt to examine the . A ball that strikes the bat does not cause it to vibrate at this point. event : evt, Bamboo bats are the lightest of the three woods, making them great for players who need to swing fast. Its harder than football, harder than baseball, harder than basketball, harder than hockey or soccer or cycling or skiing or fishing or billiards or any other of the 60 sports we rated. /N 10 0 R Some of the numbers change with actual speed, but the physics doesnt change. /R [52 73 308 791 ] The result: a harder-hit ball. White ash, sugar maple, true hickory, yellow birch, red oak, and Japanese ash are the six wood types that can be used in bats in Major League Baseball. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. } To understand such collisions it is important to first understand the physics of a collision between one ball and another. The bat breaks when large amplitude vibrations reach the thin part of the handle. /I << The fundamental mode of a wood bat has a node located typically about 17 cm from each end and a frequency typically of about 170 Hz. Then can't we add to the list of deeper queries some of . The COR for a collision between the bat and the ball is less than 0.59 when energy is lost to vibrations, but can be greater than 0.59 if the bat has a trampoline effect on the ball. endobj The batter needs to exert a small couple to get the swing started, using equal and opposite forces on the handle, otherwise the barrel of the bat will get left behind. The three elements of a game of baseball are critical, and the game is built around Newtons laws of motion. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. So, for the sake of the integrity of the game and safety, bats have remained wooden. Thick walls are also needed to help prevent the walls dinting or cracking. The COR for a collision between the bat and the ball is less than 0.59 when energy is lost to vibrations, but can be greater than 0.59 if the bat has a trampoline effect on the ball. Concentration. The science of magnetism, while not as well-known as the science of moving energy when a bat hits a ball, is still important in the game. /V 13 0 R Second, we give a simplified abstract form of bat which facilitates the description and modeling study. << A superball has a COR of about 0.9, a baseball has a COR of about 0.5 and a sorbothane ball has a COR of about 0.1 (ie it hardly bounces at all). A ball takes on a different shape as it is hit because the force of the bat pushing against it is multiplied by its mass. /N 15 0 R How is this described in Mechanics? For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. The reversal of the spin in each bounce implies that there is some tangential elastic behaviour of the ball in a direction parallel to the block. endobj A ball that would travel 400 feet in "normal" conditions goes: 6 feet farther if the altitude is 1,000 feet higher 4 feet farther if the air is 10 degrees warmer 4 feet farther if the ball is 10 degrees warmer 4 feet farther if the barometer drops 1 inch of mercury 3 1/2 feet farther if the pitcher is . While carbon dioxide gas is invisible, the very cold gas , Turbines produce noise and alter visual aesthetics. The ball is 72 mm in diameter. 2 0 obj A pitch produces a turbulent wake of air behind the ball. What is velocity of bullet in the barrel? One was a 232 gram broomstick, one was a 871 gram Louisville Slugger wood bat with four holes drilled through the barrel, and one was the 871 gram bat increased to 1333 gram by inserting a steel bolt through each hole. The sweet spot of a baseball bat Rod Cross Physics Department, University of Sydney, Sydney 2006, Australia Received 10 November 1997; accepted 22 January 1998 The sweet spot of a baseball bat, like that of a tennis racket, can be dened either in terms of a vibration node or a centre of percussion.In order to determine how each of the sweet spots inuences the ''feel'' of the . According to one study, Brazils free-tailed bats have the fastest flight speeds ever documented by flying at 160 kilometers per hour in flight. No player is perfect so all players will miss hitting in the sweet spot, so every hit could result in baseball bat damage. If you hit . endstream We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. The force of the swing is also a key factor in the performance of a baseball bat, as a hard swing can generate more power, while a softer swing can produce more control. The softball bat will vibrate mainly because it either hitting or missing the sweet spot. /Height 99 << When you use a heavier bat, the faster you hit the ball, the longer it will travel. The wall of a bat is relatively heavy and returns only some of its stored elastic energy to the ball, keeping the rest to itself so it can ping as loudly as it wants to. There is enough physics in it to keep a PhD student busy for a few years. Metal bats have the distinct composition of wood bats and the balance of pop and density that wood bats lack, whereas wood bats fly faster and farther when hit by wood bats. Also shown for comparison is a bounce off a heavy block of granite so that the COR of the ball can be determined. Near the end of the swing, the batter needs to exert a large negative couple on the bat, otherwise the bat will swing around too fast and strike the ball when it is aligned at the wrong angle. Movies showing the collision of a baseball with a cricket ball and the collision of two billiard balls are shown in the page on collisions. A lot has been learned over the years but more experiments need to be done to better understand how the ball bounces and how much spin it acquires when it bounces. The ideal is the 110 turn model. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. Baseball players were known to carve or whisk their own bats from various hardwoods during the early days of amateur baseball. /Width 77 It has been found that the swing speed for any given batter is proportional to 1/(Swing weight)^n where n is typically about 0.27 for most batters. By understanding the physics of baseball bats, players can maximize their performance on the field. Where is the center of mass in a baseball bat? The impact of a bat and a ball is still not properly understood. Hitting on the sweet spot ensures you dont lose any more energy to making vibrations inside the bat. When a baseball player hits a ball, it generates enormous amounts of energy. { >> listeners: [], This makes the game easier to pick up and more exciting to watch otherwise, every hit would only be a single. /N 13 0 R Through its shape, weight, and material composition, a baseball bat is designed to maximize a players power and accuracy while theyre at the plate. A bat with an end loaded weight indicates that it weighs between 30 and 28 ounces. The cookie is used to store the user consent for the cookies in the category "Other. the location where maximum energy is transferred to the ball. /BitsPerComponent 8 Magnetism is also an important aspect of baseball because bats use magnetite, a magnetic substance found in the body, as a means of internal navigation. The bat is 84 cm long, and has a mass of 849 gram. A simple introduction to the physics of the collision problem is given here. Collisions.- 11.Bat Performance.- 12. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. Some of our partners may process your data as a part of their legitimate business interest without asking for consent. Allow Dan Russell to explain: Any solid structure has vibrational patterns.. Colloquially, a player who hits the ball solidly is said to have gotten the sweet spot of the bat on the ball. /R [52 611 308 791 ] << When a bat is made out of a hard material, it allows the bat to transfer more energy to the ball when it is hit, enabling the ball to move faster and farther. stream << It minimizes vibration of the bat and results in the maximum energy delivered to the ball, meaning it travels the farthest. The ball seems to spin faster when it is fresh and slower after it has been used, but more experiments are needed to determine whether this is in fact correct. dKoL!8Ka#EV,@V!\j8ZFbp6EE<9cn=N6j0nf;(&;QU6bUD')c@\ Learn how to add this technique to your swing while still keeping a balanced, relaxed approach to the ball. /Filter [/ASCII85Decode /LZWDecode ] A light bat can help with dry swing training, as it can be more effective and less strenuous. The bounce was filmed at 300 fps and is played back at 30 fps in slow motion. Potential energy is what might be called stored energy. Ash bats, on the other hand, are more flexible, making them perfect for contact hitters. 5 0 obj Wood bats hit farther than metal bats, which is the clear distinction between them. These cookies track visitors across websites and collect information to provide customized ads. As the ball leaves the bat, the potential energy is converted into kinetic energy. According to Newtons third law, every action has an equal and opposite reaction. Their sweet spots are anywhere between 10.16 and 25.4 cm from the barrel end. /P 11 0 R Both papers can be downloaded here and here. How do you find the acceleration of a system? For a tennis racquet only the fundamental mode of vibration is excited by the impact since the impact duration, about 5 msec, is too long to excite higher frequency modes of the racquet. /N 6 0 R The idea is to mount a bat as a pendulum and strike it with a ball at various spots along the barrel. But strong vibrations are generated for impacts near the tip. /P 4 0 R However, there are many variables in experiments like these. << A baseball bat is shaped in such a way to have a "sweet spot." The sweet spot is due to the fact that the CP and the VN coincide. Each baseball bat has a sweet spot due to vibrational physics. (function() { Impact towards the taper region of the bat causes to bat to bend backward in the middle, and sends a vibration pulse down the handle. Thats the sport that demands the most from the athletes who compete in it. In bats made of maple wood, like the Axe Bat, it's easy to find the strongest grain. Mass has no effect on distance, but if you cant generate enough bat speed to overcome mass, you are doing yourself no favors and going backwards. Are you a fan of composite or wood? To squarely hit a fastball, everything has to . The sweet spot of a baseball bat, like that of a tennis racket, can be defined either in terms of a vibration node or a centre of percussion. Is swinging a bat potential or kinetic energy? For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. Cylinder 2 (500 Hz) Cylinder 3 (200 Hz), Compare sounds here (recorded with a signal generator connected to a speaker). Ball Trajectories.- 4. /V 15 0 R This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of its size.. Where is the Sweet Spot on a Baseball Bat? Thank you so much for. 13 0 obj When selecting a bat for the major leagues, it is critical for players to select the best wood for their bat in order to maximize performance, durability, and longevity. Upon impact with the ball, the rotation of the bat is reversed. Although the Hickory bat wood is the most difficult to swing, it is also the most powerful, making it the hardest of all bat wood species. Adair provides a few answers in his book The Physics of Baseball but he does not give the directions or the torques. 19 0 obj The batter might find that he needs to change the way he swings the bat if the swing weight is altered, or he might have a grooved swing technique and swing every bat the same way. /N 12 0 R /N 21 0 R Hence, there are two vibration nodes in the barrel. Hey, were not all headed to the majors. The ball is spinning clockwise before it bounces and hits the granite block with backspin. The experiment described below would be an ideal project on the physics of baseball, for any high school or University physics student. Do NOT follow this link or you will be banned from the site! When a very light bat is swing velocity at maximum, it has little power to transfer to the ball. Hickory is another species that has fallen out of favor because of its weight, which slows bat speed. We can then ask a similar question. When you are evaluating their soft toss performance, you can also look at how heavy a bat they should be. But I would expect there to be a difference.. Learn how the sweet spot correlates with movement and vibration. Baseball physics is based on fluid dynamics. Understanding the sizes of bats is critical to making the best choice for your game and the best bat for you. Its moment of inertia about an axis through its center of mass is 0.184 kg.m^2. window.mc4wp.listeners.push( The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. . throughout the paper. Where is the sweet spot on a bat? The result was not a super slow softball spin, neither was it particularly fast. The answer depends on how fast each bat can be swung. The stiffness of a cylinder was found to be roughly proportional to its length x (wall thickness / diameter) squared (rather than cubed, since the wall thickness is not negligible compared with the radius for most of these tubes). However. << Aluminum bats are hollow so the distribution of mass is very different than a wooden bat, which makes it much easier to swing the bat and therefore produces higher speeds and more powerful hits. You can actually hear where the sweet spot is just by tapping a bat yourself. To understand such collisions it is important to first understand the physics of a collision between one ball and another. Current research on the physics and science behind the game of cricket centers on the performance of the batsmen and bowlers. Step up to the batters box and get warmed up for the physics of baseball bats with this, You can get into the real nitty gritty of the science of MOI including complex equations by clicking through to the complete, If you have two bats, each with the same weight the bat that carries more weight in the end will perform better in terms of speed. All of these are needed to hit a baseball at the Major League level. The same batter swung the 871 g bat at 33 radians/sec on average, and he swung the 1333 g bat at 26 radians/sec on average. If the bat approaches a ball incident at speed v. Are heavy bats are more powerful than light bats? Any two connected segments can be analysed as a double pendulum. To get a better understanding of how science impacts your baseball bat, lets explore a few key scientific principles. When a ball player hits the ball with the bat, it produces an enormous amount of force on the bat in a split second - the impact could mean up to 5,000 lbs of force. The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. When the ball hits the sweet spot of the bat, the hand-held end of the bat should come to halt without receiving any impulse from the hand. << The pain of hitting away from the sweet spot motivates you to learn how to find itthat, or buy a composite bat with a vibration damper in the handle. Impact at 2 cm Impact at 7 cm Impact at 12 cm Impact at 17 cm, Impact at 24 cm Impact at 31 cm Strike at 2cm Strike at 7 cm. /V 19 0 R 12 0 obj If there is a force of 5,000lb on the ball then . hitting a baseball is either painful or frustrating. Choosing the right wood is essential for the proper performance of baseball bats. In recent years, an acoustics professor and engineer, Daniel Russell, from Pennsylvania State University helped develop a Kevlar-based vibration damper to help combat the painful sting of missing the sweet spot (only the physical sting, though). Try this: dangle the bat lightly by its knob, then use a baseball to strike the bat moving from top to bottom. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. Pitching Trajectories.- 5. This cookie is set by GDPR Cookie Consent plugin. [/CalRGB Interesting information on the behaviour of a ball can be obtained by bouncing it on a force plate or on a piezo to measure force vs time. As such, aluminum baseball bats do not have a fixed point. Materials 2' long wooden plank (a 2"x4" plank works well) U bolt Drill Smooth rod along which the U bolt can slide (e.g., shower curtain rod) Rubber mallet Tape measure Baseball bat Procedure Drill a hole through one end of the 2"x4" plank large enough to insert the U bolt. So, after a rainy day game, ensure your bat is dry before you store it. The horizontal speed at the contact point depends on the rate at which the ball spins, as well as on the horizontal speed of the centre of mass of the ball. If you hit the ball on the "sweet spot" of the bat, you get the feeling of a solid connection with the ball. It does not store any personal data. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. 1 inch in length is huge. At some point you will feel almost no vibration when you tap. 3) Care for your bat Wooden baseball bats are susceptible to cold and moisture. If the ball didn't bounce at all then COR would be zero. 22 0 obj The 232 g bat was swung at 45 radians/sec on average (by the batter in the film). As Russell explained before, there are two related ideals that we conflate into one sweet spot. The impact point 2 cm from the tip of the Easton bat is a dead spot where the ball doesn't bounce at all, so q = 0. Physicist Daniel A. Russell explains the physics of a baseball swing with a bat. Washington State University Sports Science Laboratory, You can get into the real nitty gritty of the science of MOI including complex equations by clicking through to the complete Bat-Ball Science Mass Moment of Inertia article, but well put it in laymans terms. Although playing a game of cricket requires a significant amount of time, it is filled with powerful and fast forces. The sweet spot is typically located around the center of the bat, and its size varies depending on the type of bat being used. In any collision, energy from both objects gets transferred around, but in a swing your goal is to put as much energy as possible back into the baseball. Recent Research Highlights. If the ball is struck at the sweet spot of the bat, then the batter feels almost no effect at all. These vibrations travel in waves up and down the length of the object. That said, composite and metal bats are still used by younger players who are still developing their skills. When a player has a bad hit and fails to hit the "sweet spot", it causes vibrations which can cause the bat to bend or break. /F 3 0 R The physics behind this phenomenon involves the transfer of energy from the bat to the ball. The weight of a bat can be calculated by subtracting the minus number from the length, which in this case is 33 minus -3, equaling 30 ounces. For further details, see American Journal of Physics, September 1998 and also American Journal of Physics, 69, 231-232 (2001). If you would like to change your settings or withdraw consent at any time, the link to do so is in our privacy policy accessible from our home page.. The frequency is typically between 1000 Hz and 2500 Hz, meaning that the wall vibrates in and out 1000 to 2500 times in one second. For those of us not trying to make it to the majors, using a wooden bat is mostly just a reminder that hitting a baseball is either painful or frustrating, depending on whether youve made contact with the ball or not. >> >> Well also examine the impact that technology has had on the design of baseball bats in recent years and how it has helped players to hit the ball farther and harder. It is very surprising that no one seems to have worked this out before. On average, the sweet spot occurs between 5 and 7 in (12.7 and 17.8 cm) from the barrel end of the bat. What happens to the dry ice at room pressure and temperature? Its just $1 per month , By Ball exit speed = q*vin where vin = incident ball speed. External forces are the only way to redirect the ball according to the first law of motion. A rough estimate would be that the ball rotates 1/4 revolution while it is in the pitchers hand, and while the hand moves forward say the last 0.2 m. If the hand moves forward at 10 m/s = 22.4 mph then it moves 0.2 m in 0.02 sec, so the spin rate would be 12.5 rev/s or 750 rpm. Necessary cookies are absolutely essential for the website to function properly. These cookies will be stored in your browser only with your consent. A model is developed for the collision between the baseball and bat, taking into account the transverse bending vibrations of the bat. One question that can be answered this way is "Where on the bat does the ball bounce best?" endobj It was found, by measuring the frequencies of lots of aluminum tubes (see photo). The lines behind the bat, passing through the axis, mark out angles of 5, 10, 15, 20, 25 and 30 degrees. 7 0 obj << Hit the ball at this spot, and the least amount of vibration will travel throughout the bat. /V 6 0 R Hitting the "sweet spot" is something that baseball players strive for. Analytical cookies are used to understand how visitors interact with the website. Every bat has a sweet spot.. Join PopSci+ to read sciences greatest stories. Ball exit speed = (1 + q)V where V = bat speed at impact point just before the impact. It is not difficult to swing a bat. Youre already losing about half the balls energy to deforming it (baseballs squish down to half their diameter as they impact a bat). Check out Sniper Skin's easy to install, weatherproof and dural bat grips here! This point, usually 5-7 inches from the barrel end, does not move when the bat is vibrating in its first (or fundamental) bending mode. However, it will also feel heavier when swung. The third law explains what happens to a bat when it strikes a ball. Only a small fraction of that huge force gets back to the handle to trouble the batter. As a result, the bounce is relatively weak at the tip and near the center of mass. Baseball is a beloved American pastime, with millions of people playing the game recreationally or professionally each year. The Physics of Baseball Bat Sweet-Spot. It was there that he first had the idea to create a resource for physics enthusiasts of all levels to learn about and discuss the latest developments in the field. A high-end bat is designed for major league hitters in the 31-to-32-ounce (878 to 907 grams) range. A question that is equally interesting is how the swing speed of each body segment varies as the bat speed varies and as the bat swing weight varies. The film is shown here, taken at 25 frames/sec. the location which produces maximum batted ball speed. /R [52 73 308 791 ] Regardless of age, the weight of the right handers bat is crucial. Sniper Skin carries a line of great bat grips which are easy to install and remove while virtually eliminating the sticky gunk left on your bat. The bat was swung through an axis 143 mm from the knob end. The same thing happens when swinging a golf club, but it is not a well-known effect. >> Pitching Mechanics.- 6. You can tell the bat is too heavy if the player appears to be chopping at the ball. Contacting the Ball.- 8. The above results are more or less as expected, in that light bats can be swung faster than heavy bats. 24 0 obj Swinging a Bat.- 7. Initially, the force on the handle is in the opposite direction to the motion of the handle. Experience. 3. /Length 996 /R [52 73 308 791 ] The following material has been expanded considerably into a 324 page book Physics of baseball and softball published by Springer in March 2011. Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists.
