Document Summary
Chapter 10 the special theory of relativity. Relative motion: two objects are in a relative motion whenever they have different velocities. Reference frame: the laboratory or other surroundings within which an observer makes measurements. Measurements made in a particular referenced frame are said to be relative to that frame. Special theory of relativity: einstein"s theory based on the principle of relativity and the principle of the constancy of lightspeed. In this theory, time and space are not absolute, and light has the same speed in all nonaccelerated reference frames. This theory applies only to nonaccelerated observers, whereas the general theory of relativity applies also to accelerated observers. General theory of relativity: einstein"s theory based on the principle of equivalence. In this theory, gravity is a consequence of the warping of spacetime by masses. This theory applies to accelerated observers; the special theory of relativity applies only to nonaccelerated objects.
