What is gravity?

• The upward force that acts against an object

• A noncontact force that pulls objects toward one another

• The energy an object possesses due to its speed

• A measure of the force of an object

Which term refers to the amount of matter in an object?

• Weight

• Gravity

• Mass

• Force

How is weight different from mass?

• Weight measures the amount of matter, while mass measures force

• Weight is the force of gravity on an object, while mass is the amount of matter

• Weight is constant, but mass changes based on location

• Mass depends on gravity, but weight does not

Friction is best described as:

• A force that opposes motion between two surfaces in contact

• A noncontact force that pulls objects downward

• A force that acts only on stationary objects

• A force that speeds up moving objects
