Question

what is frame of reference... plz explain in easy language

Answer 1

In physics, a frame of reference (or reference frame) consists of an abstract coordinate system and the set of physical reference points that uniquely fix (locate and orient) the coordinate system and standardize measurements.

In n dimensions, n+1 reference points are sufficient to fully define a reference frame. Using rectangular (Cartesian) coordinates, a reference frame may be defined with a reference point at the origin and a reference point at one unit distance along each of the n coordinate axes.

Answer 2

In physics,a frame of reference consists of an abstract coordinate system and the set of physical reference points that uniquely fix (locate and oreint) the coordinate system and standardize measurements.
