<P> In the case of an increase in speed from 0 to v with constant acceleration within a distance of s this acceleration is v / (2s). </P> <P> Preparing an object for g - tolerance (not getting damaged when subjected to a high g - force) is called g - hardening . This may apply to, e.g., instruments in a projectile shot by a gun . </P> <P> Human tolerances depend on the magnitude of the g - force, the length of time it is applied, the direction it acts, the location of application, and the posture of the body . </P> <P> The human body is flexible and deformable, particularly the softer tissues . A hard slap on the face may briefly impose hundreds of g locally but not produce any real damage; a constant 16 g for a minute, however, may be deadly . When vibration is experienced, relatively low peak g levels can be severely damaging if they are at the resonance frequency of organs or connective tissues . </P>
