Newton's Second Law

Newton's Second Law of Motion states...

• An object at rest will remain at rest and an object in motion will remain in motion

• the law of inertia

• An object acted on by an unbalanced force will accelerate in the direction of the force.

What is the formula for solving force?

• mass x acceleration

• force / mass

• mass x velocity

• distance / time
