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. |
