|
Both have the same amount of potential energy.

|
Neither will have more potential energy than the other.

Detailed explanation-1: -If a green golf ball is dropped from a height of 7 feet and a yellow golf ball is dropped from a height of 12 feet, which ball has greater potential energy before it is released? Both have the same amount of potential energy.
Detailed explanation-2: -Hence, when an object falls freely, its potential energy gets converted into kinetic energy. When the object hits the ground, its kinetic energy gets converted into heat energy and sound energy.
Detailed explanation-3: -When an apple falls from the tree to the ground, its energy of position (stored as gravitational potential energy) is converted to kinetic energy, the energy of motion, as it falls.
Detailed explanation-4: -So, the higher you drop the ball from, the more potential energy it has–> the more kinetic energy it has when it hits the floor–> the higher it bounces back up.
