Reference Point In Science Reference points are fixed points of origin used to measure or compare other points in science. learn about the different types of reference points in physical and social sciences, and how they impact scientific measurements and research. Teacher support [bl] [ol] you may want to introduce the concept of a reference point as the starting point of motion. relate this to the origin of a coordinate grid. [al] explain that the reference frames considered in this chapter are inertial reference frames, which means they are not accelerating.

Learn the meaning of reference point as something that is used to judge or understand something else. see how to use the word in sentences from various sources and related entries. Reference frame: any arbitrary reference point and associated definition of three orthogonal axes, with respect to which the position of all other points may be defined, constitutes a reference frame. it is typically defined by specifying the position of the reference point and direction of the axes. Thus, by definition, "a fixed point with respect to which a body changes its location is called reference point or origin." when dealing with calculations in kinematics, reference point is usually the origin of the coordinate system, no matter whether the system is 1, 2 or 3 dimensional.
