On Earth, the rate at which things fall (gravitational acceleration) is 9.8 m/s2. On the Moon, it is approximately 1.6 m/s2.
Note: m/s2 (meters per second per second) means that for every second...
Well... not exactly. The Moon is constantly accelerating towards the Earth, but its sideways velocity is great enough that it never actually gets there. This is more or less the definition of "orbit".
