An important distinction in waves is between the phase and group descriptions of this. In relativity, its values cannot be added directly. The square root of "two GM over r" describes one form of this, and "mg over b" describes another, caused by air resistance. Those formulas respectively correspond to the (*) escape and terminal forms of it. This quantity's derivative is acceleration. For 10 points, name this vector quantity that describes the rate of change of position.
