Physics for IGCSE & O level - Forces And Motion (Section 8 - No. 21)
What is Newton's third law of motion?
For every action, there is an equal and opposite reaction.
An object at rest stays at rest, and an object in motion stays in motion with the same speed and in the same direction unless acted upon by a force.
Force is equal to the change in momentum per change in time.
Objects fall at the same rate regardless of mass.
