Consider the diver and the diving board. Which object exerts the action force? which object exerts the reaction force? in what direction does the action force push? in what direction does the reaction force push?
The Correct Answer and Explanation is:
In the context of a diver on a diving board, the action and reaction forces are part of Newton’s Third Law of Motion, which states that for every action force, there is an equal and opposite reaction force. Let’s break it down:
1. Action Force:
The action force is the force exerted by the diver on the diving board. When the diver pushes down on the board, they apply a downward force to it. This is the action force.
2. Reaction Force:
The reaction force is the force exerted by the diving board on the diver. According to Newton’s Third Law, the board will exert an equal and opposite force on the diver. This force is directed upward, pushing the diver off the board.
3. Direction of the Action Force:
The action force, which is the force the diver applies to the board, is directed downward. This happens when the diver presses down on the board with their weight.
4. Direction of the Reaction Force:
The reaction force, which is the force the board applies on the diver, is directed upward. This force is equal in magnitude but opposite in direction to the force the diver applies on the board. This upward force is what propels the diver into the air after they push off the board.
Explanation:
Newton’s Third Law of Motion states that forces come in pairs. In this case, the diver exerts a downward force on the diving board when they push off. The board, in turn, exerts an equal and opposite force on the diver, which is directed upward. This upward force (the reaction force) causes the diver to leave the board and move through the air.
The action-reaction pair between the diver and the board is essential for the diver’s jump. The diver’s push downward on the board causes the board to push upward with an equal force, propelling the diver into the air. The strength and speed of the diver’s push on the board will determine how high and fast they will rise, showcasing the practical application of Newton’s Third Law in real-life scenarios like diving.
