Momentum in Relativity

, where:

p = Momentum ((kg*m)/s)

 = Lorentz Factor

m = Mass (kg)

v = Velocity (m/s)

Relativistic Energy

For an object in motion,  

 , where:

E = Energy (J)  

 = Lorentz Factor

m = Rest Mass (kg)

c = Speed of Light (m/s)

Relativistic Mass

 , where:

m = Relativistic Mass (kg)

 = Lorentz Factor

m0 = Proper mass, Rest mass (kg)

Speed of Light

 , where:

c = Speed of Light (m/s)

Time Dilation

 , where:

t' = Time interval for observer (s)

t = Proper time in rest frame (s)

 = Lorentz Factor
