Short Duration Shock and Jerk
Short term shocks may be caused by impacts, drops, earthquake, or explosion. Shock is a short-term transient excitiation and is often measured as an acceleration. Very short duration shocks of 100 g have been survivable in racing car crashes.
Jerk is the rate of change of acceleration. In SI units, jerk is expressed as m/s3.

Famous quotes containing the words short, duration, shock and/or jerk:
“I cannot be a materialist—but Oh, how is it possible that a God who speaks to all hearts can let Belgravia go laughing to a vicious luxury, and Whitechapel cursing to a filthy debauchery—such suffering, such dreadful suffering—and shall the short years of Christ’s mission atone for it all?”
—D.H. (David Herbert)
“This pond never breaks up so soon as the others in this neighborhood, on account both of its greater depth and its having no stream passing through it to melt or wear away the ice.... It indicates better than any water hereabouts the absolute progress of the season, being least affected by transient changes of temperature. A severe cold of a few days’ duration in March may very much retard the opening of the former ponds, while the temperature of Walden increases almost uninterruptedly.”
—Henry David Thoreau (1817–1862)
“There are persons who, when they cease to shock us, cease to interest us.”
—F.H. (Francis Herbert)
“One farmer says to me, “You cannot live on vegetable food solely, for it furnishes nothing to make bones with;” and so he religiously devotes a part of his day to supplying his system with the raw material of bones; walking all the while he talks behind his oxen, which, with vegetable-made bones, jerk him and his lumbering plow along in spite of every obstacle.”
—Henry David Thoreau (1817–1862)
