What is Newton's First Law of Motion?

• F=M X A

• The Law of Inertia

• Force means a push or pull

• You must clean up Gail's classroom daily.

What is Inertia?

• An object at rest will move and an object in motion will stop.

• Objects are lazy.

• An object at rest will stay at rest, and an object in motion will stay in motion unless acted upon by an outside force.

• F=M X A
