How many important laws are in Newton's laws of motion?

The correct answer is that there are three important laws in Newton's laws of motion. These laws form the foundation of classical mechanics and describe the relationship between the motion of an object and the forces acting on it.

The first law, often called the law of inertia, states that an object at rest will stay at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force. This law introduces the concept of inertia, which is the tendency of an object to resist changes to its state of motion.

The second law provides a quantitative description of the effects of forces and states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This is often expressed with the formula ( F = ma ), where ( F ) is force, ( m ) is mass, and ( a ) is acceleration.

The third law states that for every action, there is an equal and opposite reaction. This law emphasizes the interactions between objects and explains how forces always come in pairs.

Together, these three laws provide a comprehensive framework for understanding motion and force in physical systems. The other options suggesting different quantities do not accurately reflect the established principles set forth
