Question

which of the following is an example of newtons third law of motion? a a plate sitting on a table with unbalanced forces acting in the opposite direction b a ball rolling down a hill, with balanced forces c a person pushing against a wall, and the wall pushing back with an equal force in the opposite direction

Explanation:

Newton's third - law states that for every action, there is an equal and opposite reaction. In option C, a person pushing against a wall is the action force, and the wall pushing back with an equal force in the opposite direction is the reaction force. Option A describes an unbalanced - force situation not related to Newton's third law. Option B describes a situation with balanced forces but not an action - reaction pair as per Newton's third law.

Answer:

C. A person pushing against a wall, and the wall pushing back with an equal force in the opposite direction
