Newton’s Third Law explains how forces work in pairs. It says that whenever you push or pull on something, that object pushes or pulls back with the same force in the opposite direction. This is called action and reaction. This law helps us understand how things move and interact in the world.
- Action and Reaction Forces: For every force you apply, there is an equal opposite force.
- Examples: When you sit on a chair, your body pushes down, and the chair pushes up.
- Everyday Impact: It helps explain flying birds, shooting guns, and jumping off boats!
