Geodesic (general Relativity) - Coordinate Time

Coordinate Time

So far the geodesic equation of motion has been written in terms of proper time, s. It can also be written in terms of the time coordinate, . The equation then becomes:

x''_a(t) = \left(\Gamma^{bc}_a-x'_a(t)\Gamma^{bc}_0\right)x_b'(t)x_c'(t)

This can be useful for commuter calculations and to compare General Relativity with Newtonian Gravity.

Famous quotes containing the word time:

    “When people ask for time, it’s always for time to say no. Yes has one more letter in it, but it doesn’t take half as long to say.”
    —Edith Wharton (1862–1937)
