6. identify the action-reaction pairs of forces for the following situations: (a) you step off a curb. (b) you pat your tutor on the back (c) a wave hits a rocky shore.
examples of action and reaction
To identify the action-reaction pairs of forces for each situation, we need to determine the forces involved and understand Newton's third law of motion. Newton's third law states that for every action, there is an equal and opposite reaction.
(a) When you step off a curb, there are two forces involved. The action force is the force applied by your foot on the curb, pushing it down. The reaction force is the force exerted by the curb on your foot, which pushes your foot upward.
(b) When you pat your tutor on the back, again, there are two forces involved. The action force is the force applied by your hand on the tutor's back, pushing it forward. The reaction force is the force exerted by the tutor's back on your hand, pushing it backward.
(c) When a wave hits a rocky shore, there are also two forces involved. The action force is the force applied by the wave on the rocky shore, pushing it inwards. The reaction force is the force exerted by the rocky shore on the wave, pushing it backward or reflecting it back into the water.
It's important to note that the action and reaction forces occur on different objects. The action force is exerted on one object, while the reaction force is exerted on a different object in the opposite direction.
