Newton’s Third Law
Easyphysics
According to Newton’s Third Law, when a swimmer pushes water backward with her hands, the water:
Select the correct option:
Solution
Incorrect! Answer:
Exerts an equal forward force on the swimmer
- Newton’s Third Law: For every action, there is an equal and opposite reaction.
- Action-Reaction Pair: The forces always act in pairs, on different bodies, and in opposite directions.
- Application: The swimmer exerts a force on the water (Action, backwards). Simultaneously, the water exerts a force on the swimmer (Reaction, forwards).
- Outcome: The magnitudes of these two forces are identical. The forward force from the water is what allows the swimmer to move through the pool.
