Understanding Newton's Laws of Motion

What does Newton's First Law of Motion state?

• An object in motion will eventually stop due to friction.

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

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

• Force equals mass times acceleration.
