Question
A man hits another man with his hands on his jaw. This is the action force. What is the reaction force?
- Force exerted by another man’s jaw on the hands.
- Force exerted by the audience.
- Force exerted by hands on another man.
- Force exerted by anger.
Hint:
Action-reaction force
The correct answer is: Force exerted by another man’s jaw on the hands.
- The third law states that for every action there is an equal and opposite reaction.
- The two bodies will experience each other's reaction forces in opposite directions.
- A man hits another man with his hands on his jaw. This is the action force.
- Therefore, force exerted by another man's jaw on the hands is the reaction force.
