Which of the following Newton's law(s) is/are not applicable in non-inertial reference frame.

  • A. Newton's first law
  • B. Newton's second law
  • C. Newton's third law
  • D. All of these

Step-by-step solution

In non-inertial (accelerating) reference frames, fictitious forces appear. Newton's first law (inertia) fails because objects can accelerate without a net real force. Newton's second law (F = ma) fails unless fictitious forces are added. Newton's third law (action-reaction) fails because fictitious forces lack a reaction counterpart. Thus, none of Newton's laws are directly applicable in non-inertial frames without modifications.
