Question

You are riding a roller coaster. At what point in the ride is the system in a state of equilibrium?

Answer 1

Answer:

When the rider is at the top of the roller coaster.

Answer 2

Answer:

Gravitational potential energy is greatest at the highest point of a roller coaster and least at the lowest point. Kinetic energy is energy an object has because of its motion and is equal to one-half multiplied by the mass of an object multiplied by its velocity squared.

Explanation:

From what majority science textbooks say is that potential energy is when an object has the ability to move, but it doesn't... that is not word for word, but I hope it helps.
