Question

MEDAL AND FAN CHECK ANSWER

Which of the following energy changes occurs as a ball bounces?
Potential to chemical
Magnetic to kinetic
Thermal to mechanical
Kinetic to potential****

Answer 1

Kinetic energy is when something is moving, potential energy is when energy is stored.
e.g. Stretching a rubber band creates potential energy.
So, correct me if I am wrong, I believe you are correct.

Answer 2

i think its thermal to mechanical not sure if its that
