Question

Elizabeth is pushing against a wall as she stretches before exercising as shown below. The wall pushes back against Elizabeth's hands with the same force in the opposite direction. Which of Newton's laws does this best demonstrate? A. Newton's universal law of gravitation B. Newton's third law of motion C. Newton's second law of motion D. Newton's first law of motion

Answer 1

Newton's third law of motion

Step-by-step explanation:

According to Newton's third law of motion, for every action force there is an equal and opposite reaction force. In this case, the action force is Elizabeth pushing against the wall with her hands. As this happens, there is an equal and opposite reaction force in which the wall pushes back on Elizabeth's hands.
