When a bouncy ball is dropped from a height and bounces back from the floor, it has the following engery conversion
When a bouncy ball is dropped from a height and bounces back from the floor, it undergoes the following energy conversions:
1. Potential Energy to Kinetic Energy: Initially, when the ball is at a height, it possesses potential energy due to its position relative to the ground. As it falls towards the ground, this potential energy is converted into kinetic energy, which is the energy of motion.
2. Kinetic Energy to Elastic Potential Energy: When the ball hits the floor, the kinetic energy is transferred into the ball's material, causing it to compress. This compression stores potential elastic energy within the ball.
3. Elastic Potential Energy back to Kinetic Energy: The stored potential energy within the ball is then released, causing the ball to deform and rebound off the floor. As the ball returns to its original shape, this potential elastic energy is converted back into kinetic energy, allowing the ball to bounce back upward.
4. Kinetic Energy to Potential Energy: As the ball bounces back, its kinetic energy decreases, and potential energy starts to increase again due to its height above the ground.
This cycle continues as the ball bounces multiple times, with energy being converted between potential energy, kinetic energy, and elastic potential energy. However, it's important to note that some energy is also lost in the form of heat due to air resistance and internal friction within the ball, resulting in a gradual decrease in the height and bounce height over time.
