What is the rate of change in an object's speed called?

Back

Acceleration

Front

What do we call the way that something causes a change?

Back

Action

Front

What is the tendency of a physical object to remain still or continue moving unless a force is applied?

Back

Inertia

Front

What term describes the size or quantity of something?

Back

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F=ma).

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is the term for the force that opposes the motion of an object?

Back
