A swimmer that pushes the water back with feet and arms what is the reaction force?
What is the action force?
What will happen to the movement of the swimmer as they push the water back?
If the swimmer exerts 5 n of force on the water how much force does the water exert back on the swimmer?
Please help with questions
The reaction force to a swimmer pushing the water back with their feet and arms is the water pushing the swimmer forward. This is known as Newton's third law of motion - for every action, there is an equal and opposite reaction.
The action force in this situation is the swimmer exerting force on the water by pushing it backward with their feet and arms.
As the swimmer pushes the water back, the water exerts an equal and opposite force on the swimmer, propelling them forward in the water.
If the swimmer exerts 5 N of force on the water, then according to Newton's third law, the water will exert an equal and opposite force of 5 N back on the swimmer.
To understand the concepts of action and reaction forces in the context of a swimmer pushing the water back with their feet and arms, let's break it down:
1. What is the reaction force?
In accordance with Newton's third law of motion, the reaction force is the force exerted by the water in response to the swimmer's action. In this case, as the swimmer pushes the water back with their feet and arms, the reaction force is the force exerted by the water in the opposite direction, pushing the swimmer forward.
2. What is the action force?
The action force, in this case, is the force exerted by the swimmer on the water while pushing it back with their feet and arms.
3. What will happen to the movement of the swimmer as they push the water back?
As the swimmer pushes the water back, according to Newton's third law, the water exerts an equal and opposite reaction force on the swimmer. This reaction force pushes the swimmer forward in the water, propelling them in the opposite direction of their push.
4. If the swimmer exerts 5 N of force on the water, how much force does the water exert back on the swimmer?
According to Newton's third law, the reaction force exerted by the water on the swimmer will be equal in magnitude but opposite in direction to the action force exerted by the swimmer. Therefore, if the swimmer exerts 5 N (Newtons) of force on the water, the water will exert an equal and opposite 5 N of force back on the swimmer.
