A swimmer that pushes the water back with feet and arms what is the reaction force?

What is the action force?

What's doing the aciton? The arms and legs.

What is reacting? the water pushes back.

Thank you!

In this scenario, when a swimmer pushes the water back with their feet and arms, the reaction force is the force exerted by the water on the swimmer. This reaction force propels the swimmer forward through the water.

The action force, on the other hand, is the force exerted by the swimmer on the water. As the swimmer kicks and strokes, they apply a force on the water in the opposite direction they want to move. According to Newton's third law of motion, for every action, there is an equal and opposite reaction. So, the reaction force (exerted by the water on the swimmer) pushes the swimmer forward through the water.

To summarize:
- Action force: Force exerted by the swimmer on the water.
- Reaction force: Force exerted by the water on the swimmer.
