Term
 The law of conservation of energy needed to be redefined as the law of conservation of matter and energy as a result of Einstein's equation, which is stated mathematically as ______.
Definition
 E=mc2. This equation describes the convertibility of matter into energy and vice versa.
Term
 In the formula used to calculate relativistic mass, what is the relationship between mass and velocity?
Definition
 Mass increases when velocity increases. It has been shown in particle accelerations that mass increases as we approach the speed of light.
Term
 Accoring to the theory of relativity, as an object approaches the speed of light, what happens to time, space, and mass?
Definition
 Time expands, space contracts, and mass increases. As you approach the speed of light, time slows down, length decreases, and mass increases.
Term
 As an object is continuously uniformly accelerated, its velocity approaches the speed of light. How is the mass affected, if at all?
Definition
 The mass of the particle will increase. As a particle is accelerated, mass will continue to increase, based on theories of relativistic mechanics.
