Newton’s third law worksheet (Action-Reaction)
Try to answer the questions below. Then, look on the answer sheet to see the
correct response. Good luck!
1. A diver dives off of a raft – what happens to the diver? The raft? How does
this relate to Newton’s Third law?
2. A tennis racquet hits a tennis ball. Why doesn’t the racquet swing backwards
when the ball hits it? (Shouldn’t it swing back because of action-reaction
forces?)
3. What action-reaction forces are involved when a rocked engine fires? Why
doesn’t a rocket need air to push on?
4. What forces are acting on a book sitting on a table? Are action-reaction forces
involved in this situation?
5. If two people each standing on a scooter board push off of each other what
happens (relate to Newton’s third law)?
6. In 5 how would the distance moved by the scooter boards compare if one
person had a lot more mass than the other person?
7. If a person standing on a scooter board pushes off of a wall, what happens?
Can this situation be explained in terms of Newton’s third law (action-reaction)?
8. How is shooting a shotgun related to Newton’s third law?
