Front

What does inertia refer to in terms of motion?

Back

The tendency of an object to remain at rest or in uniform motion unless acted upon by an external force.

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).

How does mass affect the acceleration of an object when a force is applied?

Back

Greater mass results in less acceleration for the same amount of force applied.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F=ma).
