Which has more GRAVITATIONAL POTENTIAL energy and WHY? (Choose the BEST explanation!)

A roller coaster car at the top of a hill

OR

a roller coaster car at the bottom of the hill.

• The car at the top because it is not moving, so it has more potential energy.

• The car at the top because it is higher off the ground, so it has more GPE.

• The car at the bottom because it is going faster.

• The car at the bottom because it can't go any lower.

A plane flying above the ground has what energy?

• Only GPE because it is high

• Only KE because it is moving

• GPE and KE because it is off the ground and moving
