WebShock (mechanics) A mechanical or physical shock is a sudden acceleration caused, for example, by impact, drop, kick, earthquake, or explosion. Shock is a transient physical excitation. 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). Websince the shock is assume inﬁnitely thin and therefore the area of the ﬂow is the same on both sides. • Momentum normal to the shock: p1 +ρ1q 2 N1 = p2 +ρ1q 2 N2 (Bom2) • …
