What is Newton's Third Law?

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

• F = MxA

• An object at rest stays at rest unless acted upon by an outside force

• Speed= Distance/Time

Which of the following best shows Newton's Second Law?

• An object in motion stays in motion unless acted upon by an outside force

• There is an equal & opposite reaction for every action

• force = mass x acceleration

• force = sound x acceleration

An object at rest stays at rest & an object in motion stays in motion unless acted upon by an outside force.
