When is potential energy transformed into kinetic energy?

• When an object at rest is lifted to a higher elevation
• When an object at rest remains at rest
• When an object at rest is put into motion

• Mass

• Stretch

Which has more GRAVITATIONAL POTENTIAL energy?

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.
