love_444 (Mariana V.I.P): Motion of body is described with respect to some well defined coordinate system, which is known as “Frame of Reference”. IT'S OF TWO TYPE 1). Inertial frame of reference 2). Non-inertial frame of reference *

love_444 (Mariana V.I.P): Inertial frame of reference :- In this frame bodies not acted upon by external force, is at rest or moves with constant velocity and obey Newton’s law of inertia *

love_444 (Mariana V.I.P): Non-inertial frame of reference :-In this frame , bodies not acted upon by any external force, is accelerated not obey Newton’s law of inertia. *

love_444 (Mariana V.I.P): Newtonian Principle of Relativity :-laws are valid in one reference frame, then they are also valid in another reference frame moving at a uniform velocity relative to the first system. *
