In physics, a shock wave (also spelled shockwave), or shock, is a type of propagating disturbance that moves faster than the local speed of sound in the medium. Like an ordinary wave, a shock wave carries energy and can propagate through a medium, but is characterized by an abrupt, nearly discontinuous, change in pressure , temperature , and ...
The term "SWF" originated as an abbreviation for ShockWave Flash. [8] This usage was changed to the backronym Small Web Format to eliminate confusion with a different technology, Shockwave, from which SWF derived. [9] [10] There is no official resolution to the initialism "SWF" by Adobe. [11] Adobe declared its Flash player EOL on December 31 ...
An oblique shock at the nose of a T-38 aircraft is made visible through Schlieren photography. An oblique shock wave is a shock wave that, unlike a normal shock, is inclined with respect to the direction of incoming air.
Shocks are characterized by discontinuous changes in flow properties such as velocity, pressure, temperature, etc. Typically, shock thickness is of a few mean free paths (of the order of 10 −8 m). Shocks are irreversible occurrences in supersonic flows (i.e. the entropy increases).
Conical shockwave with its hyperbola-shaped ground contact zone in yellow. A sonic boom is a sound associated with shock waves created when an object travels through the air faster than the speed of sound. Sonic booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear.

According to an article in the journal Toxicological Sciences, . Blast overpressure (BOP), also known as high energy impulse noise, is a damaging outcome of explosive detonations and firing of weapons.
The Shockwave was a staple at air shows and dragstrips nationwide, including in North Carolina. It offered rides to fighter pilots and, sometimes, to reporters.
