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)

What happens to an object in motion if no forces act on it?

Back

It continues to move at a constant velocity.

Front

Back

An external force is a force acting on an object from outside the object itself.
