1. Lesson 5:
Action and Reaction -
Newton’s Third Law

2. Newton’s Third Law of Motion
For every action (or force), there
is a equal and opposite reaction (or force).

3. This means that forces occur in pairs.
When a baseball player hits the ball, a force is applied to the bat in the direction toward the batter, while a force is applied to the ball in the direction away from the batter.
