Vibration G-force Definition and Calculation. So called G-force, it is actually not a force. G-force is an acceleration expressed using G as the unit. G is referred to as the acceleration of gravity, which equals 9.81m/s 2 at the sea level. Acceleration of an object is defined as the rate of its velocity change (Δv) in a given period of time
