Witryna1 sty 2016 · However, thanks to its high density – a robust 5.427 g/cm3, which is just slightly lower than Earth's 5.514 g/cm 3 – Mercury has a surface gravity of 3.7 m/s 2, which is the equivalent of 0.38 ... WitrynaThe unit of measure of acceleration in the International System of Units (SI) is m/s 2. However, to distinguish acceleration relative to free fall from simple acceleration (rate of change of velocity), the unit g (or g) is often used.One g is the force per unit mass due to gravity at the Earth's surface and is the standard gravity (symbol: g n), defined as …

WitrynaAt Earth’s 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.
