Quizplus · Accepted Answer

According to Einstein's equation E=mc², energy and mass are equivalent. As an object approaches the speed of light, its kinetic energy increases, and therefore its mass increases. This phenomenon is known as relativistic mass. According to the special theory of relativity, as the speed of a rocket ship increases, the mass of the spaceship increases as well. This is known as relativistic mass, and it is a result of the increase in kinetic energy as the velocity of the spaceship approaches the speed of light. As the spaceship approaches the speed of light, the relativistic mass approaches infinity.
