Combining SR and GR time dilation

  1. Mar 12, 2009 #1
    Just seeking a bit of guidance if I may ?

    If Lambda 1 is the time dilation caused by a gravitational field (ie proper time outside field/proper time inside field for static observers), and Lambda 2 is the usual time dilation under special relativity for a moving body (both lambda's >= 1), how should I combine them for a moving particle in a gravitational field, is is additive, multiplicative or some other combo ?
