Relativistic momentum approaches infinity as the velocity of an object approaches the speed of light. approaches speed of light (c). (See Figure 1) This is another indication that an object with mass cannot reach the speed of light. If it did, its momentum would become infinite, an unreasonable value. Example: An electron, which has a mass of 9.11 x 10-31 kg, moves with a speed of 0.750c. Find its relativistic momentum.
