“How High can a Basketball Bounce”

Research Paper:
The goal of this experiment is to determine which surface and height allows the basketball to bounce the highest. My initial idea of performing the experiment is to test bouncing a basketball ball on different surfaces and to drop the basketball from different heights reaches . During my experiment I will conduct 5 trials of dropping the ball at 40 inches on four different surfaces. The next trial I will perform will be to test how high the ball bounces when dropped on to the concrete from different heights. I will drop the ball starting at 4 feet and increasing the ball dropping by 6 inches to eventually drop the ball at 6 feet. …show more content…

When a basketball is held in the air, it has potential energy and no kinetic energy. When it starts to fall, it starts to losing potential energy and gaining kinetic energy. The bounce factor between a basketball and bowling ball is different in many ways, basketball is inflated with air and made with rubber that are able to bounce with a force on it. Bowling balls are made out of dense hardwood that are not able to bounce. Many more ways that affects a way the ball bounces are the height which the ball is dropped, the ball’s level of inflation, the temperature of the outside, and the surface the ball bounces on. Different surfaces equals different bounce. The surface when a ball is bounced also changes shape when the ball drops on it. Springier surfaces changes more as a ball hits it and saves the molecules inside the ball so it does not flatten. Soft surfaces absorbs most of the ball’s energy and stops the ball from bouncing back. The knowledge gained by the research of my topic was that there is three different types of energy when using a basketball. When the ball is held it is potential, when the ball hits the ground it is

PACE TECHNICAL PAPER ROUGH DRAFT This experiment was conducted in an attempt to have wooden baseball bats brought back to NCAA and high school and children’s leagues, too. The experiment idea was to set up a pendulum where the bat swung down and hit the ball in the same spot every time. Then I measured where the ball hit the ground.

However, they may have different amounts of it when they both bounce because of the way they are made. One’s rubber may be stretched or compressed in a way that gives it more elasticity or bounce so that when it hits the racquet or court it bounces higher. Tennis balls have less elastic energy than golf balls so one may think they have less elastic potential energy than racquetballs on average. Also, with the tennis ball weighing more and still having enough elastic energy to bounce as high as the lighter racquetball it is right to say that the tennis ball has more elastic potential energy. Finally, gravitational energy is the last main type of energy that affects tennis.

My project is about how temperature and air pressure affect the distance a football can be thrown. When the air is warmer the molecules move faster and spread apart, therefore making the air pressure lower and making the ball lighter. But when the air is cooler the molecules move slower and move closer together, making the air pressure higher making the ball

How does temperature affect the bounce of a tennis ball My science fair project is about tennis balls and temperature. I chose this topic because I am interested in how temperature affects how high a tennis ball bounces. When the ball hits the floor it expands and when it comes up then it comes back up it contrasts. My question that is going to be answered is,how does temperature affect the bounce of a tennis ball?

I used a stopwatch to measure the time in seconds. I measured the time from when I threw the ball in the air until it landed back on the ground. I faced two problems while testing my hypothesis. One problem I faced was trying to avoid hitting the cars parked in my driveway with the balls. One of the balls did hit the car, but luckily it didn’t damage the car.

The application of force in the delivery of a pitch directly influences its speed and movement. By understanding how different forces act on the ball during its release, we gain insight into the relationship between force and speed (Newton's Laws of Motion, 2023). In application of the previously discussed forces of pitching lies the Magnus effect. The Magnus effect is responsible for the spinning of the ball in the air, but how? When the ball is traveling through the air from a pitch, one side is traveling in the direction of the air flow, while the other is traveling in opposition to it.

Then it changes when it starts going down. Then when going down the velocity changes and does something different. my conclusion is when the ball is going up there is two ways of velocity. Then when it gets to the top it turn equals, after that when it is going down it changes the way of velocity when it was going

Kevin Irwin Physics SL: Period 7 May 5th, 2017 Measuring the Backspin of a Baseball and the Maximum Height Reached Exploration: Introduction: Projectile motion is a form of motion in which an object is thrown near the earth’s surface, and moves alone a curved path under the action of gravity only. It is implied that all other external forces, such as air resistance and drag, are neglected, and gravity is the only force acted upon the object, in a downward motion. Due to Newton’s first law of Inertia – “Every object persists in its state of rest or uniform motion in a straight line unless it is compelled to change that state by forces impressed on it” (Philosophiæ Naturalis Principia Mathematica) – there is no horizontal force needed to maintain

Bouncing may be a significant segment in the material science behind basketball. As a basketball player hops circulating everywhere to settle on An shot he could show up with make suspended to mid-air Throughout the high pitch of the bounce. This may be an outcome about projectile movement. When a article is tossed buzzing around it will Invest an extensive rate of time in the Main and only the Toss. A b-ball player could hop to the extent that 4 feet buzzing around (vertically).

In the data, one trend found was that as the ball became closer to the ground, it’s kinetic energy value went up and the GPE value went down. Also, when the ball went up, the value of kinetic energy became smaller and the value of GPE became greater. This is correct because when any object is close to the ground the kinetic energy is greater than the GPE and when the object is at it’s highest point the GPE is greater and the kinetic energy is less. Another trend was when the ball was at the very end or beginning the total energy was .5 off from the total energies of the points in the middle. This is an example of inherent error because there was no way for the LabQuest to get the exact point and motion, so the calculations were bound to be

CHAPTER: (1) Introduction 1.1 Problem Summary and Introduction: The goal for our group is to design a ping pong ball launcher. The launcher needs to be scheduled to launch one solo ping pong ball one at a time over a set obstacle and into a bucket of a chosen diameter. The determination is for the launcher to have the capability to launch five ping pong balls one at a time into the container within one minute, having none of the ping pong balls bounce out or miss the bucket. The launcher can be made out of any matter preferred and can launch the ping pong ball in any anticipated way, except by explosion.

Physics gives us an understanding of how the world operates, which is why the efficiency of a balls bounce can be understood through investing the principles of physics. Before a ball is dropped, it has gravitational potential energy acting upon it, when it is dropped the energy is transferred to kinetic energy. When the ball hits the ground the kinetic energy is transferred to elastic potential energy, once the ball regains its shape, it changes back to kinetic energy. As the ball rebounds higher into the air, kinetic energy is changed into gravitational potential energy. When a ball rebounds it doesn’t return to the original height it was dropped as energy has been wasted through heat in each transfer.

When the ball hits the ground its kinetic energy is turned into elastic energy this makes the ball flatten out. Then that elastic energy is converted right back into kinetic energy when it goes up. So the more kinetic energy a ball gets when it is dropped the more energy it will have when it hits the ground which will give it more energy when it is headed back up therefore making it bounce higher.
