Which of the following is true about newton's laws of motion?
Correct answer: C. All of them are related to forces
- A. One of them is not related to forces
- B. Two of them are not related to forces
- C. All of them are related to forces
- D. One of them is related to forces
Explanation
Newton's laws of motion are all related to forces. The first law (Law of Inertia) describes how an object remains at rest or in uniform motion unless acted upon by a force. The second law quantifies how the force applied to an object is proportional to its acceleration (F=ma). The third law states that for every action, there is an equal and opposite reaction, highlighting the interaction of forces between two bodies. Each law explains different aspects of the influence of forces on motion, making option C correct. Options A, B, and D are incorrect as they mistakenly suggest that not all of the laws are related to forces.

About Force and Motion
Displacement, velocity and acceleration describe motion, including the horizontal and vertical components of projectile motion. The chapter connects these quantities with Newton's laws, momentum and impulse, then applies conservation of momentum to collisions, distinguishing elastic collisions from inelastic ones.
