WebDefinition. The Lorentz factor γ is defined as = = =, where: v is the relative velocity between inertial reference frames,; c is the speed of light in vacuum,; β is the ratio of v to c,; t is coordinate time,; τ is the proper time for an observer (measuring time intervals in the observer's own frame).; This is the most frequently used form in practice, though not the … WebQ. If two object collide and one is initially at rest (a) Is it possible for both to be at rest after collision. (b) Is it possible for any one to be at rest after collision. Ans. (a) No, because momentum will not be conserved in that case. (b) Yes, when masses of two object are equal and collision is perfectly elastic.
