Physical Science Exam Review

False: elastic

COMPRESSION energy is stored in a stretched rubber band.

False: mechanical

ELASTIC energy is the total potential and kinetic energy in a system.

False: kinetic

Energy in the form of motion is POTENTIAL energy.

True

Energy is measured in JOULES.

True

Energy stored in food you eat is CHEMICAL POTENTIAL energy.

False: potential

Energy that is stored is KINETIC energy.

False: gravity

When a ball is dropped, it falls down due to the force of FRICTION.

True

When you put on the brakes of a bicycle, friction causes some of the mechanical energy to CHANGE to thermal energy.

True

A book sitting on a shelf has GRAVITATIONAL POTENTIAL energy.

True

A box doesn't move when you push it because of STATIC friction.

False: potential

A rock at the edge of a cliff has KINETIC energy because of its position.

False: can't

According to the law of conservation of energy, energy CAN be created or destroyed.

True

According to the law of conservation of energy, mechanical energy can be CHANGED to heat energy.

False: sliding

Pushing a box up a hill, you have to overcome STATIC friction.

False: stronger

The greater an object's mass, the WEAKER the gravitational force on it.
