Newton's laws do not hold good for particles, which
Correct answer: D. Move with a velocity comparable to the velocity of light
- A. Are at rest
- B. Are moving slowly
- C. Move with high velocity
- D. Move with a velocity comparable to the velocity of light
Explanation
Newton's laws of motion do not apply to particles moving at velocities comparable to the speed of light. At such high velocities, according to Einstein's theory of special relativity, the laws of classical mechanics formulated by Newton fail to accurately describe the behavior of particles.

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.
