Question

A ball is dropped from a height of 150cm. The ball has a gravitational potential energy of 5j (Joules) before it was released. As the ball falls to the flour, the gravitational potential energy and kinetic energy change.

Determine the gravitational potential energy, kinetic energy, and total energy when the ball reaches a height of 90cm as it falls. Assume no energy is transferred to the air as thermal energy.

Answer 1

When the ball falls, some of its gravitational potential energy is converted to other forms of energy, such as kinetic energy and rotational energy. When it rebounds, these other forms of energy is converted back to gravitational potential energy.
