Velocity Transformation Rules

Back to Special Relativity


 Recall the Lorentz transformation 

 

The differential version of Eq. (1) is

 

From the definition of velocity  

 

 

 

Eqs. (3) to (5) are the transformation laws for velocity. The inverse transformation is obtained from Eqs. (3) to (4) by interchanging primes and the sign of v to give 

 

 

 

To obtain the transformation law for g ‘ we simplify Eqs. (3) to (5) by dividing by c to give

 

where ak º uk/c.  We wish to find  

 

Substituting the relations in Eq. (5) into Eq. (6) results in
