Term that describes the strength of relativistic effects as an object attains a significant percentage the speed of light.

Gamma (g) is determined as follows:

g = 1/((1 - (V^2)/(c^2))^1/2)

With V equalling the object's velocity as measured by an outside observer, and c, of course, being the velocity of light, both expressed in equivalent terms for this purpose. For example, if V equals 0.8665c, then g equals 2.
