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 forces
Explanation
Newton's laws of motion can be paraphrased as follows: 1. A body remains at rest, or in motion at a constant speed in a straight line, unless acted upon by a force.2. When a body is acted upon by a force, the time rate of change of its momentum equals the force.3. If two bodies exert forces on each other, these forces have the same magnitude but opposite directions.All of these laws describe the relationship between the motion of an object and the forces acting on it.

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.
