What to do: If you have two balls that are the same, drop them from the same height at the same time. They should hit the ground together (or at slightly different times depending on how well you hold them up to the same height and drop them at the same time).
What factors affect the bounce height 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.
Why do balls bounce higher when dropped from a greater height?
Because the ball is softer than the floor, it does most of the denting and stores most of the energy. 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.
How does drop height affect bounce height?
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 happens when you drop a ball?
When you drop the ball, gravity pulls it down and it picks up speed. It hits the ground and squashes at the moment of impact. As the squashed ball springs back to its original shape, it pushes on the floor and the floor pushes back. The force of the floor pushing against the ball throws the ball back up into the air.
What happens when a ball is dropped?
How does air pressure affect the bounce of a ball?
As the air becomes more squished, it pushes more on the inside of the ball. With more air in the ball, the air starts at higher pressure and pushes back that much harder when the ball is bounced. So that short answer is that more inflated basketballs bounce better because they have more air pressure inside them.
Why was it important to drop the ball from the same height three times?
Explanation: When all three balls are dropped from the same height, the rubber ball will bounce the highest because it has the greatest elasticity. This is because the higher the starting height of the ball, the higher the ball’s potential energy.
Why was it important to drop the ball from the same height three times why were the numbers slightly different?
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.
How did the GPE change with height?
Since the gravitational potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of the gravitational potential energy. A tripling of the height will result in a tripling of the gravitational potential energy.
What energy transformations occur when a ball is dropped?
As the ball falls towards the ground, its potential energy is transformed into kinetic energy, which will continue increasing as it gains momentum, until it finally collides with a surface.
What happens to potential energy when a ball is dropped?
If an object is going to be dropped from high up in the air, it has lots of potential energy because the earth’s gravity has plenty of time to accelerate, or speed up, the ball when you let go of it—and the longer an object falls, the faster it gets.
How can you increase the accuracy of the experiment?
This help to greatly increase the accuracy of the experiment. Drop a ball from 1 foot off of the floor, slightly in front of a yardstick. Measure the height the ball reaches after the first bounce and record. Repeat this test from 2 ft, 3 ft, and 1/2 ft. Do this test for each ball and record data.
How do you record the results of an experiment?
In your lab notebook, make a data table like Table 1, and record your results in it by checking off which ball hit first. If you recorded your trial, view the video recording to verify your results. For any experiment, it is important to do multiple trials to assure that your results are consistent.
