How does a bouncing ball lose energy?
When a ball hits a wall or surface, it makes a noise, which is a loss of energy from the ball’s bounce. It also will generate some amount of heat, another loss of energy. Friction from the wall will cause energy loss as well as air resistance while the ball travels.
How do you calculate average bounce height?
MATERIALS: Tennis ball, meter stick. Step 1: Drop the ball from 100 cm. Measure how high it rebounds after the first bounce. Repeat three times, then find the average height after one bounce.
What is the effect of drop height on the rebound height of a ball?
If the drop height increases, then the resulting bounce height will also increase, because as the drop height increases, so does the gravitational potential energy which can be converted back into kinetic energy on the rebound.
What is the relationship between drop height and bounce height?
The relationship between drop height and bounce height is only linear for small drop heights. Once a ball reaches a certain height, the bounce height will begin to level off because the ball will reach its terminal velocity.
Can you pop a basketball?
Basketballs don’t really pop, actually. Not usually. One of my shots once took a funny bounce off my driveway hoop, a car ran over the ball and it popped extraordinarily loudly. Like a gunshot, almost.
What is the best air pressure for a basketball?
8.5 pounds per square inch
Does the size of a basketball affect how high it bounces?
The size of the ball can affect its bounce due to air resistance, surface volume and density. However, mass can also play a part in how a ball bounces. If two balls contain the same mass, but are of different sizes, the larger ball will bounce less due to greater air friction against its surface.
What affects the bounce of a ball?
The combination of the material properties of a ball (surface textures, actual materials, amount of air, hardness/ softness, and so on) affects the height of its bounce.
How many times can a ball bounce?
In an idealized situation with a fixed coefficient of restitution between 0 and 1, a ball bounces an infinite number of times in a finite amount of time and travels a finite abount of total distance, with the frequency of bounces approaching infinity as the time approaches the limit of time based on the initial …
Why was it important to drop the ball from the same height three times?
Answer: It is important to do this to test your theory multiple times, so that you can see what effect the drop has on it when doing this multiple times. The numbers were slightly different because the recordings will not always be the same.
Do heavier balls bounce higher?
Both balls will fall at a similar speed, but because kinetic energy is proportional to the mass of the object, the heavy ball reaches Earth with more energy. It will not necessarily rebound higher, as it also needs more kinetic energy to reach a specific height again.
How Does height affect the bounce of a ball?
Thus a typical ball bounces to 60% of its original height because it stores and returns 60% of the energy it had before the bounce. When you drop a ball from a greater height, it has more kinetic energy just before it hits the floor and stores more energy during the bounce—it dents farther as it comes to a stop.
What is the rebound height?
The Synthetic Turf Council (STC) and FIFA recommend that a soccer ball rebounds to a height between 60 to 100 centimeters on a community field, and 60 to 85 centimeters on a stadium field. These ranges are based on a comprehensive study done on natural turf fields.
What causes a ball to bounce higher?
The faster an object moves, the higher its kinetic energy. A lot of it goes back into the ball, giving it more force to pop back up into the air—so the higher the potential energy, the higher the kinetic energy, and the higher the kinetic energy, the higher the bounce!
How many times will a ball bounce before coming to rest?
The series of heights is infinite, so before stopping, the ball must bounce an infinite number of times. #1.
Why does a ball bounce less on carpet?
When a basketball bounces off of a surface, some of its energy is absorbed by that surface. A hard surface, such as concrete, absorbs less energy compared with a soft surface, such as a carpeted floor. The more energy absorbed by the surface, the less that remains in the ball for it to bounce.
When a basketball bounces against the ground and gets deformed and then recovers its shape?
When a basketball bounces against the ground and gets deformed and then recovers its shape, the air inside that ball is temporarily compressed and will again have its original volume when the ball recovers during the rebound.
How high should an NBA ball bounce when dropped?
about 1.80 m
Does density affect bounce height?
Density does affect the bounce height (to some extent), in particular, due to air drag: the higher the density, the less significant is the effect of air drag.
How do you measure rebound height?
Just using these two measurements, I can find the rebound ratio. Using the geometric sequence formula, we have 111=200(r)(2−1). 200 represents the initial height, and (2, 111) represents the second height after the first bounce at 111 cm. We now know that this ball has a 55.5% rebound ratio.
What surface does a ball bounce best on?
As the ball is released, gravity pulls the ball downwards and transforms that potential energy into kinetic energy, the energy of motion. The harder the court surface is the more energy a dropped ball retains and the higher it rebounds. A basketball bounces pretty well on hardwood, but even better on concrete.
How does the temperature of a tennis ball affect the height of its bounce?
When the temperature increases, the gas molecules inside the tennis ball expand. As the molecules expand, their energy increases as they bounce around more erratically. This increased energy and movement results in a higher bounce. As a result, a cold ball has a much lower bounce.
How does temperature affect the restitution of a bouncing ball?
The temperature of the ball influences its coefficient of restitution. A warmer ball will bounce higher than a cold one.
How do you measure the bounce height of a ball?
Paint each of the balls with poster paint in a circle around the ball so that you can hold the ball on both sides to bounce it. Stand 1 meter from the wall. Measure this distance using a meterstick. Bounce each ball toward the wall without using any of your own force.
Why does a ball bounce lower each time?
Since the height to which the ball will bounce is directly proportional to its energy (barring effects of air friction), with a coefficient of restitution of less than one the ball will bounce less and less high.
Does the amount of air in a basketball affect the shot?
The air pressure in a basketball can’t affect how you play and how good your shot is. Ones shot can defer at anytime and it really doesn’t depend on the air pressure in the ball. We can’t prove this because we miss shots even when the balls is perfectly inflated.
Why does my basketball keep losing air?
Basketballs tend to lose a little air when left unused and through normal use over time. In order to bounce properly, basketballs need the right amount of air pressure. To get the most out of your basketball it is very important to keep it at its recommended air pressure, and to inflate and deflate it correctly.
Does temperature affect bounce height?
One factor that can influence the bounce of a ball is the temperature of the ball. A warmer ball will bounce higher than a cold one. The reason for this is twofold. In a hollow ball, the change in temperature causes a change in air pressure within the ball.
