The famous horse and cart physics scenario is explained. This scenario is employed to describe why most of the people have a common misconception regarding what Newton’s Third Law states and does not say. Use this scenario to explain how people try to argue that no object should move if Newton’s Third Law and Second Law were correct (that is, if all forces encompass an equal and opposite force, then there would be no total force and if there is no net force then no objects should move). At first write out the confused logic the horse uses. Second, write out the accurate logic. Finally, explain the significance of external forces acting on a system (in this case the external forces acting on the cart and horse).
Q1. Determine the logic the horse uses?
Q2. What is the horse stating wrongly?
Q3. Describe the external forces acting on the horse and cart?
