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.
