Newton's Law REVIEW

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

Acceleration is produced when a force acts on a mass. The formula is Force = Mass x Acceleration.
