G-Force

GS}}
The g-force or gravitational force equivalent is mass-specific force (force per unit mass), expressed in units of standard gravity (symbol g or g₀, not to be confused with "g", the symbol for grams).
It is used for sustained accelerations, that cause a perception of weight. For example, an object at rest on Earth's surface is subject to 1 g, equaling the conventional value of gravitational acceleration on Earth, about .
More transient acceleration, accompanied with significant jerk, is called... plus
