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.
