notes
Newton’s Third Law
To every action, there is always an equal and opposite reaction.
For example, when you hold the ball, a force acts on the ball (Action), and an equal and opposite force acts on your hand (Reaction).
Action & Reaction forces always act on different bodies
- FAB = FBA
- FAB: Force acting on A by B
- FBA: Force acting on B by A
Action & Reaction forces occur at the same instant
