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?”

Question

Definition Definition Fundamental law of forces which states: “For every action, there is an equal and opposite reaction." In other words, whenever one body exerts a force on a second body, the second body exerts an oppositely directed force of equal magnitude on the first body. It is also called the “action-reaction law” and was defined by Sir Isaac Newton.

An illustration shows an overhead view of a car as it approaches a fork in the road. The car is oriented such that it is directed toward the top of the illustration. A force F1 extends from the nose of the car and points along the left-side forked road at an angle of 10° measured counterclockwise from the car's initial direction. A force F2 extends from the nose of the car and points along the right-side forked road at an angle of 30° measured clockwise from the car's initial direction. Two forces are applied to a car in an effort to move it, as shown in the figure below. (Let F1 = 440 N and F2 = 366 N. Assume up and to the right are in the positive directions.)

10 of 31 Listen Study the scenario. A car is moving along a frictionless surface with a speed of 2 m/s to the left. You and your friend each come over and push the car at the same time. You exert a force of 6 N to the left, while your friend exerts a force of 6 N to the right. According to Newton's first law, how will this action affect the car's motion? The car will speed up because your force is in the same direction of the car's motion, making it speed up. The car will stop immediately because two balanced forces will cause an object to stop moving. The car will continue moving to the left but at a slower speed because your friend's force is going to make the car slow down. The car will continue to move 2 m/s to the left because there are balanced forces acting on it.
