Reference point is too important in physics.

Relative motion definition. 1 having meaning or significance only in relation to something else; There is no such thing like absolute motion or absolute rest. The relative term is not conferring to earth but is basically.

Relative motion refers to the motion or speed of any object in respect to a particular point. We define two reference frames, one inertial and one moving. The position of p relative to the inertial frame is given by r and relative to the moving frame is r rel.

Relative motion is the study of moving object with respect to other object in motion; Relative motion is the motion which is computed on the grounds of motion of an object in contrast to another moving motion. Relative motion we always have to define the position of any particle or object with respect to some reference point to measure any change or variation in it.

The position of the origin o. Relative motion can be termed as the motion of an object with respect to some other object either at rest or in motion, that is, either moving or stationary. Therefore, \[\vec{v}_{ps} = \vec{v}_{ps'} + \vec{v}_{s's} \ldotp \label{4.35}\] the velocity of a particle.

Relative motion is the motion compared to some frame of reference other than ground and when the motion is defined with respect to the ground, the frame of reference. The concept of relative motion refers to the comparison of two rigid bodies' relative accelerations and velocities. When earth rotates on its axis, it’s relative to the motion which it revolves around the earth.

Motion as observed from or referred to some material system constituting a frame of reference (as two adjacent walls and floor of a room) — see relativity. It is always relative ; Relative motion refers to the motion or speed of any object in respect to a particular point.
