Newton's law of motion cannot be applicable to the particles

GP Motion Force

Newton's law of motion cannot be applicable to the particles moving at a speed comparable to the speed of

  1. light
  2. sound
  3. rocket
  4. bullet train


Newton's laws of motion are for applicable to matter, which occupy some space and have some mass. It is not possible for any matter to travel with the speed of light. Secondly, the mass changes as the speed approaches the speed of light. Newton's law is applicable only when mass is constant.

The correct option is A.
