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?”

Once you reach the 21st floor you decide that your urge to understand physics is too great so you decide to ride the elevator back to the ground floor to analyze what happens. The elevator accelerates downward at 2 m/s2. What is the Gravitational Force? Since the elevator is accelerating downward does the Normal Force have to be greater than, equal to or less than the Force of Gravity? Are the forces balanced or unbalanced? Draw a free body diagram of the forces acting on you. Be sure to draw the size of your arrows appropriately. What is the Net Force, using Newton’s 2nd Law, while the elevator is accelerating downward? What is the Normal Force? What does the scale read as the elevator is accelerating downward
