Standard acceleration of gravity in the context of "Shock (mechanics)"

In mechanics and physics, shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation. A mechanical shock typically consists of a short-duration, high-magnitude acceleration event that can cause structural deformation or failure in components.

Shock describes matter subject to extreme rates of force with respect to time. Shock is a vector that has units of an acceleration (rate of change of velocity). The unit g (or g) represents multiples of the standard acceleration of gravity and is conventionally used.
