What is potential energy?

• The stored energy of an object due to its position or condition.

• The energy that an object has due to its motion.

• The energy an object has due to its speed.

• The energy an object has due to its volume.

What is kinetic energy?

• The stored energy of an object due to its position or condition.

• The energy that an object has due to its motion.

• The energy an object has due to its speed.

• The energy an object has due to its volume.

Which passenger has the most potential energy?

• A

• B

• C

• D

When is kinetic energy transferred from object to object?

• When those objects pass one another

• When the first object outweighs the second object

• When the first object has more potential energy than the second object

• When those objects collide

What does the law of conservation of energy tell us?

• Energy is created and destroyed all of the time.

• Stars generate most of the energy on the earth.

• Energy can not be created or destroyed.

• Dark matter absorbs most of the energy in the universe.

When does an object have no kinetic energy?

• When it is at rest

• When it is moving very slowly

• When the only force acting on it is gravity

• When it has no electrical charge

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.
