Newton's Third Law

Newton's Third Law made obvious — every action force produces an equal and opposite reaction you can see and feel.

How it works

1. Apply an action force on the model
2. Observe the equal, opposite reaction
3. Compare the two forces

What students learn

• State Newton's Third Law (action–reaction)
• Identify action–reaction pairs
• Explain recoil and propulsion

Try these experiments

1. Show an action and its reaction
2. Find action–reaction pairs around you
3. Relate to rockets and recoil
