In the supermarket you return a cart to the cart area. You stand still and push the cart towards the other carts. You've just learned that the cart pushes back on you too, according to Newton's Third Law. a. Explain why the cart moves and you do not.

The cart moves and I do not because for every action there is an equal and opposite reaction.

Equilibrium. Action, Give an example of Newton's third law acting in everyday life
