Answer:
a sky diver who is midway through his descent to the ground
a roller coaster car halfway down the second hill
a falling raindrop
Explanation:
From the law of conservation of energy, it can neither be created nor destroyed but can be converted from one form to another.
The sum of kinetic energy and potential energy is mechanical energy. A body has potential energy due to its position or configuration and kinetic energy due to its speed.
A body can have both potential energy and kinetic energy.
The correct options are:
- a sky diver who is midway through his descent to the ground
-
a roller coaster car halfway down the second hill
- a falling raindrop
A boulder resting on top of a mountain has just potential energy.
A parked car also has just potential energy.
