The amount of matter in an object.

A measure of the force of gravity on an object.

The tendency of an object to resist a change in motion.

Newton's first law of motion

The scientific law that states that an object at rest will stay at rest and an object in motion will stay in motion with a constant speed and direction unless acted on by a force.
