### g-Acceleration Calculator - Linear Motion

g-Acceleration Calculator - Linear Motion. Calculation of the g-force at accelerating or braking in a straight line motion. 1 g is the average gravitational acceleration on Earth, the average force, which affects a resting person at sea level. 0 g is the value at zero gravity. 1 g = 9.80665 m/s² = 32.17405 ft/s².
