Newton's First Law of Motion

A force that opposes, or pushes back against, an object moving past another object

• gravity

• friction

• inertia

• mass

An object at rest will stay at rest unless an unbalanced force acts on it.

• True

• False

An object that is changing position (location) is

• at rest

• in motion

An object's tendency to resist (not) change its state of motion.

• gravity

• force

• inertia

• friction

If an object in motion is not acted on by an unbalanced force, it will continue with the same speed and direction.

• True

• False

If an object is speeding up, it is accelerating.

• True

• False
