Unformatted text preview: —+— I The classical deﬁnition of momentum, p=mv, is not adequate to describe the
momentum of objects moving close to the speed of light. The classical deﬁnition
of momentum ieads to violations of Conservation of Momentum for collisions
described in one inertial refetence frame after the velocities are transformed using the tools of Special Relativity into another reference frame. I Relativistic momentum is the product of gamma [y - NW] and mu. As
such, the magnitude of relativistic momentum is not directly proportional
to speed. If the speed of an object is near the speed of light, the change
in relativistic momentum for increasing increments of speed becomes very
great. For a mass to obtain the speed of light requires an inﬁnite change in its
momentum, and as the velocity approaches c, the acceleration of the object
due to applied force approaches zero. I At speeds much lower than the speed of light, the relativistic momentum
approaches the classical value. OLDER TEHTEAND SIEHE OUTLINE SUPPLEHEHTS MULTIPL‘I' GMMM FHTCI THE MASS WT‘I'; EM].—
