Is ball bouncing between two vertical walls is SHM?

In a bouncing ball, the speed only becomes zero gradually at the top of the bounce. The speed changes abruptly at contact with the ground. Hence it is not simple harmonic.

Why does the height of bouncing ball decreases after each bounce?

Each time the ball hits the floor, a fraction of the ball’s energy is lost as internal friction (the ball squeezes) turning into heat. It will then return upwards with a little less energy than it started out with. As a result the ball never reaches its starting height again.

Why is a bouncing ball not an example of SHM?

A bouncing basketball can not have harmonic motion – either damped or undamped. In order to create harmonic motion, a force has to depend on something’s position. This is the same no matter where the object is so it can’t be harmonic motion.

How Does height affect the bounce of a ball?

A: The height to which a ball will bounce depends on the height from which it is dropped, what the ball is made out of (and if it is inflated, what the pressure is), and what the surface it bounces from is made out of. A ball’s gravitational potential energy is proportional to its height.

Which of the following is example of SHM?

Bungee Jumping is an example of simple harmonic motion. The jumper oscillating up and down is undergoing SHM due to the elasticity of the bungee cord. The back and forth movement of the cradle is caused due to a single push and is maintained by the principle of SHM, and hence, causing the baby to sleep.

Which one of following is SHM?

Earth spinning about its axis.

How does the height to which the ball bounces compare to the height from which it was dropped?

For multiple bounces, it’s just like dropping the ball again from a reduced height. So if f is 0.9, the first bounce will be 0.9 times as high, the second 0.81 times as high, the third 0.729 times as high (as the original height), and so on. Try it yourself!

Does the height of a tennis ball drop affect the height of the bounce?

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.
