Description
Newton's inertial frame of reference
Two frames of reference moving with relative velocity . Frame S' has an arbitrary but fixed rotation with respect to frame S. They are both inertial frames provided a body not subject to forces appears to move in a straight line. If that motion is seen in one frame, it will also appear that way in the other.
Within the realm of Newtonian mechanics, an inertial frame of reference, or inertial reference frame, is one in which Newton's first law of motion is valid.[28] However, the principle of special relativity generalizes the notion of inertial frame to include all physical laws, not simply Newton's first law.
Newton viewed the first law as valid in any reference frame that is in uniform motion relative to the fixed stars;[29] that is, neither rotating nor accelerating relative to the stars.[30] Today the notion of "absolute space" is abandoned, and an inertial frame in the field of classical mechanics is defined as:[31][32]
An inertial frame of reference is one in which the motion of a particle not subject to forces is in a straight line at constant speed.
Hence, with respect to an inertial frame, an object or body accelerates only when a physical force is applied, and (following Newton's first law of motion), in the absence of a net force, a body at rest will remain at rest and a body in motion will continue to move uniformly�that is, in a straight line and at constant speed. Newtonian inertial frames transform among each other according to the Galilean group of symmetries. https://en.wikipedia.org/wiki/Inertial_frame_of_reference
