• A battery before it's used

• A bird flying through the air

• Food before it's eaten

What is potential energy?

• The energy an object has due to its motion.

• The energy stored inside an object with the potential to move or change.

• The energy produced by friction.

• The energy that is always destroyed.

What factor primarily determines an object's gravitational potential energy?

• Its color.

When a roller coaster is at the very top of a hill, what type of energy does it primarily possess, and what does it convert to as it goes down?

• Kinetic energy, converting to thermal energy.

• Potential energy, converting to kinetic energy.

• Electrical energy, converting to sound energy.

• Chemical energy, converting to light energy.

What happens to some of a roller coaster's mechanical energy due to friction as it moves along the track?

• It is destroyed completely.

• It is converted into electrical energy.

• It changes into heat and sound energy.

• It increases the roller coaster's speed indefinitely.
