On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earthâs mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects. At Earthâs surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second. At the surface of the Moon the acceleration of a freely falling body is about 1.6 metres per second per second.
