A roller coaster track is a good example of the law of conservation of energy. Use this law to explain these facts about a roller coaster track. a. The largest hill for a roller coaster track is the first hill on the track. The hills after the first are smaller and smaller. b. To get to the top of the first (highest) hill, a motor pulls the cars up to the top. After the top of the first hill, a motor is not needed to keep the cars going. c. The roller coaster car moves really fast at the bottom of a hill on the track but slows down as it moves up a hill (not including the first hill).

The fact is that a roller coaster car moves really fast at the bottom of a hill on the track but slows down as it moves up a hill. Option C is correct.

What is the law of conservation of energy?

According to the law of conservation of energy, the energy of an isolated system stays unchanged throughout time; it is said to be conserved.

Energy cannot be created nor destroyed and can be transferred from one form to the other form.

As energy cannot be created nor be destroyed and can be transferred from one form to the other form. The energy is converted from potential energy to kinetic energy.

Potential energy is due to the position.While the kinetic energy is due to the motion. As the roller coaster approaches the hill, the velocity decreases.

A roller coaster vehicle runs very quickly at the bottom of a hill on the track, but it slows down as it progresses up the slope.

Hence, option C is correct.
