When the roller coaster is going up the hill, the potential energy (stored energy) is increasing and once at the top of the hill the potential energy is at its highest point becuase the velocity Is almost zero. Once the rollercoaster falls and speeds down the hill, the potential energy is converting to kinetic energy because of the movement. Kinetic energy is moving energy and potential energy is stored energy.

False .........................................
Answer:
Option (a) is the correct answer.
Explanation:
The law of conservation of energy states that energy can neither be created nor it can be destroyed. It can only be transformed from one form to another.
Therefore, the total amount of energy before and after a chemical reaction is the same. Thus, energy is conserved.
Therefore, we can conclude that option (a) is the correct answer.
