Answer:
about to be dropped-------------gravitational potential energy
falling down.................................Kinetic energy
hitting the floor.............................potential energy
moving back up...........................Kinetic energy
Step-by-step explanation:
When the ball is about to be dropped it possesses potential energy.This is the energy stored in an object.When the ball is released, the potential energy will be converted to kinetic energy.Kinetic energy is the energy an object has due to its motion.When the ball hits the floor, energy is lost in form of siund and heat.The kinetic energy when falling will be transformed to potential energy which is lesser than the initial one when the ball was about to be dropped.The ball bounces back after hitting the floor.The potential energy is converted back to kinetic energy .
