Question

the diagram shows a person applying an action force to a diving board. a diver pushes down on a diving board. the board pushes the diver upward. which statement best applies to the forces? the reaction force acts in the same direction as the action force. the reaction force acts in the opposite direction to the action force. the reaction force is greater than the action force. the reaction force is not as large as the action force.

Explanation:

According to Newton's third - law of motion, for every action, there is an equal and opposite reaction. When the diver pushes down on the diving board (action force), the board pushes the diver upward (reaction force). The reaction force acts in the opposite direction to the action force and has the same magnitude.

Answer:

The reaction force acts in the opposite direction to the action force.
