Efficient and safe transportation depends on friction being either minimized or maximized, as necessary. Using research, find  a) one example in which friction is maximized to aid in transportation. b) one example in which friction is  minimized to aid in transportation. For each situation, explain how the friction is maximized/minimized and why this is necessary or beneficial.

Newton’s Third Law of Motion

The horse pulls the cart and the cart pulls the horse in response as per Newton third law. So the big question is, “Don’t the two forces cancel each other? How does the cart accelerate?”
