Newton’s Third Law Of Motion MDCAT Quiz with Answers

Newton’s Third Law of Motion is among those principles of physics that are well known and highly relevant for MDCAT students preparing for the medical and dental entrance exam. The law states that for every action, there is an equal and opposite reaction. In other words, whenever an object exerts a force on a second object, the second object exerts a force of equal magnitude but in the opposite direction on the first object. This principle is fundamental to the interaction of forces, hence it is a critical topic in the MDCAT Quiz.

Understanding Newton’s Third Law of Motion

Newton’s Third Law applies to all interactions between objects, be it with contact forces—such as pushing or pulling—or forces at a distance, such as gravitational or magnetic forces. The classic example is the rocket: as the engines expel gas downwards, an equal and opposite reaction force propels the rocket upwards. This law also explains why you feel a pushback when you push against a wall. In problems involving MDCAT, identification of action-reaction force pairs is very important; one must realize that the forces are exerted on different objects, not on the same one.

MDCAT Quiz: Newton’s Third Law of Motion Questions

Many of the questions on the MDCAT Quiz involving Newton’s Third Law involve its real-life applications in calculating forces, particularly in systems where objects interact with each other. For example, students might be asked to find the force exerted by a car’s tires on the road and the corresponding reaction force of the road on the tires. Other scenarios include analyzing the motion of objects in systems where forces are exchanged, like pulling a rope or colliding objects. By practicing these problems, MDCAT students come to understand the practical implications of the law and develop a systematic approach to answering questions about forces.
