Multiple Choice

A roller coaster car has a lot of potential energy as it sits at the top of the first hill. This energy is converted to kinetic energy when the car begins its first drop. That kinetic is converted back into potential as the car ascends the second hill. Based on this, what happens to the energy of the roller coaster car as it moves along the track?

• It is lost completely

• It is transformed between potential and kinetic energy

• It disappears at the bottom of the hill

• It only increases

Multiple Choice

What is energy transformation?

• The process of energy changing from one form to another.

• The process of storing energy in a battery.

• The process of using energy to create wealth.

• The process of losing energy to the environment.
