Final answer:
When you push on a wall, the wall pushes back on you with an equal amount of force according to Newton's 3rd law of motion.
Step-by-step explanation:
According to Newton's 3rd law of motion, if you were to push on a wall, the wall will push back on you with an equal amount of force. This is because every action has an equal and opposite reaction. So, when you exert a force on the wall, the wall exerts the same amount of force back on you, causing you to feel a push.
