Explain what happens to the potential energy of a rock as it falls off the side of a cliff.

• The kinetic energy decreases as the potential energy increases.
• The kinetic energy decreases as the potential energy decreases.
• The potential energy decreases as the kinetic energy increases.
• The potential energy decreases as the kinetic energy decreases.

Matches, batteries, gasoline, and food are all examples of ________________________.

• gravitational potential energy

• elastic potential energy

• chemical potential energy

• None of the above

If a green golf ball is dropped from a height of 7 feet and a yellow golf ball is dropped from a height of 12 feet, which ball has greater gravitational potential energy before it is released?

• yellow

• green

• Both have the same amount of potential energy.

• Neither will have more potential energy than the other.

The picture best demonstrates

• As kinetic energy increases, potential energy decreases

• kinetic energy and potential energy are always equal

• As kinetic energy decreases, potential energy decreases

Why does a car accelerate as it round a corner at a constant speed?

• Its direction changes
• It doesn't
• It slows down
• Its speeds up
