Re: [Phys-l] Invariant mass and relativist mass...





|
| Are you applying this to all three spatial components of p and V?
|
| Bob at PC


A quick reply without thinking too much is Yes; for all three spatial
component directions.

in the expressions below, v and p are vectors (spatial part of
four-vectors) either version of m and gamma are scalars.

|
| Do you prefer to write your relativistically correct momentum formula
| as:
|
|
| a) p = gamma*m*v
|
|
| or
|
|
|
| b) p = m*v
|
|
|
| If you like (b) you are preferring a relativistic mass approach.
|
| If you like (a) you are preferring an invariant mass approach.
