Question

For this question, consider the changes in energy the ball undergoes as it (1) is in the air just before impacting the floor, (2) while it is impacting the floor, and (3) just after it leaves the floor and is in the air again. a.) What types of energy are present while the ball is in the air just before impacting the floor? What is happening to each of these types of energy as the ball moves closer to the floor? What is happening to the total energy at the same time? b.) While the ball is impacting the floor, there will be kinetic energy, gravitational potential energy, elastic potential energy (stored in the ball as it compresses against the floor), sound energy, vibrational energy, and heat. What force is removing the gravitational potential energy and kinetic energy from the ball and converting it into these other forms of energy? What happens to the energy of the ball (gravitational potential energy and kinetic energy) while the ball is in contact with the floor?

Explanation / Answer

1 Just before impacting it have only kinetic energy 2 . while impecting it have elastic potential energy 3. Just after leaving the floor it have only kinetic energy

a. only kinetic energy b. while ball is impacting there is elastic potential energy

Compressive force is removing gravitational potential energy and kinetic energy

While ball is in contact with floor its total kinetic energy and potential energy converts into elastic potential energy
