Ram Pressure

(pressure on a body moving through a fluid)

Ram Pressure is pressure exerted on a body due to its movement through a fluid. It is:

P = ρv²
  • P - pressure
  • ρ - density of the fluid
  • v - velocity of the body relative to the fluid

Examples:

In the latter case, the pressure can strip away the galaxy's interstellar gas (Ram-pressure Stripping).

Compression from the high pressure heats a gas, and for an object moving sufficiently fast, such as meteors or space vehicles entering the atmosphere, the compression contributes more heat than does the friction.
