Answer: A roller coaster at the top of a hill JUST BEFORE it goes over the edge is an example of potential energy.
Step-by-step explanation:
An energy that is acquired by an object due to its motion is called kinetic energy.
An energy that is acquired by an object due to its position is called potential energy.
For example, when a roller coaster at the top of a hill JUST BEFORE it goes over the edge has only potential energy because it is not in motion.
The energy present in the roller coaster is due to its position that is being at the top of a hill.
Thus, we can conclude that a roller coaster at the top of a hill JUST BEFORE it goes over the edge is an example of potential energy.
