Which would have the LEAST gravitational potential energy (GPE)?

• A ball sitting on the ground

• Moon viewed from the Earth

• An airplane flying 30,000 feet above the ground

• A rock sitting on top of Mt. Everest

How could you increase the gravitational potential energy of an object without changing its mass and gravity?

• Make the object larger

• Lower the object towards the ground

• Raise the object farther off the ground

• Allow the object to roll on the ground

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 does a yo-yo have the most potential energy?

• When it's at its highest point.

• When it's at its lowest point.

• When it's moving between its highest and lowest points.

• When it's moving at its top speed.

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.
