Invalidation of Newton's law

  1. May 3, 2010 #1
    why the newton's law of motion are only valid in inertial frame of reference, not in non-inertial frame? since force like Coriolis force are not considered for these laws.

    The Coriolis force is an example of a fictitious force that needs to be added when viewing things from a rotating frame in order to apply Newton's laws. Fictitious forces only appear in accelerating reference frames.

    Hi astro2cosmos! :smile:

    In a non-inertial frame, Newton's laws of motion are valid if we allow fictitious forces such as centrifugal force and Coriolis force …

    that is what the fictitious forces were invented for, to make Newton's laws work! :wink:
