Newton's Third Law says:

• For every action there is an equal and opposite reaction

• An object at rest and an object in motion will stay in motion until acted on by an outside force.

• Force=Mass x Acceleration

Newton's First Law says:

• Force=Mass x acceleration

• An object at rest stays at rest and an object in motion stays in motion until acted on by an outside force.

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

Newton's Second Law says:

• Force = Mass x acceleration

• An object at rest stays at rest and an object in motion stays in motion until acted on by an outside force.

• For every action there is an equal and opposite reaction
