Question

if the wall does not move, which law explains why the person still feels a force pushing back?
law of gravity
newtons first law
newtons third law
newtons second law

Explanation:

Newton's Third Law states that for every action, there is an equal and opposite reaction. When the person pushes on the wall, the wall exerts an equal - magnitude force back on the person. The Law of Gravity is about the force between masses. Newton's First Law is about an object's motion when no net force acts on it, and Newton's Second Law relates force, mass, and acceleration.

Answer:

Newton's Third Law
