Answer : The reference point in physics is referred to as a point or object in a particular space according to which the position of an object is defined in that space. It is generally used to determine the motion in a specific area. It is a fixed position that does not move and according to which the object’s movement is described. The action is described in the coordinates concerning the reference point. The reference point is considered as a stationary and comparative point that defines the coordinates. Considering the three axes, a, b and c, the intersection area of all the three axes, their origin, is known as a reference point in physics.
