What is potential energy?
The energy an object has due to its atomic structure.
The energy an object has due to its chemical composition.
The energy an object has due to its motion.
The energy an object has due to its position or condition.
When does an object have no kinetic energy?
When it's at rest.
When it's moving very slowly.
When the only force that's acting on it is gravity.
When it has no electrical charge.
Which object has the most potential energy?
A ball resting on the ground.
A ball being thrown at 100 miles per hour.
A ball on top of a refrigerator.
A ball resting on the edge of a cliff.
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.
When an object in motion is stopped and put at rest.
Four cars are positioned at the top of a hill. Which car has the most potential energy?
A
B
C
D
Why do objects at high elevations have more potential energy than objects at low elevations?
Because the thinner air at higher elevations means objects have a greater potential to move very fast
Because objects at high elevations are closer to the sun, which is the source of all energy on earth
Because objects at high elevations tend to move slower than objects at low elevations
Because gravity gives objects at high elevations the potential to fall much further

How does the mass of a bowling ball that has been rolled down the lane affect the kinetic energy?
The kinetic energy does not depend on the mass of the bowling ball.
The kinetic energy is increasing proportional to the mass of the bowling ball.
The kinetic energy is decreasing proportional to the mass of the bowling ball.
The kinetic energy is increasing proportional to the square of the mass of the bowling ball.
