Physics for IGCSE & O level - Forces And Motion (Section 11 - No. 25)

Which of the following is a correct statement of Newton's Third Law?

Force = mass * acceleration.

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

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

The greater the mass of an object, the greater its inertia.

Newton's Third Law states the equal and opposite reaction.
