In physics, ram pressure is a pressure exerted on a body which is moving through a fluid medium. Physics (Greek Physis - φύσις in everyday terms is the Science of Matter and its motion. FLUID ( F ast L ight '''U'''ser '''I'''nterface D esigner is a graphical editor that is used to produce FLTK Source code It causes a strong drag force to be exerted on the body. In Fluid dynamics, drag (sometimes called fluid resistance) is the force that resists the movement of a Solid object through a Fluid (a

For example, a meteor traveling through the Earth's atmosphere produces a shock wave generated by the extremely rapid compression of air in front of the meteoroid. For the music album by Converter see Shock Front For the 1977 horror film see Shock Waves A shock wave (also called It is primarily this ram pressure (rather than friction) which heats the air which in turn heats the meteoroid as it flows around it. Friction is the Force resisting the relative motion of two Surfaces in contact or a surface in contact with a fluid (e [1]

In the case of a galaxy moving through the intergalactic gas, the ram pressure is capable of stripping the galaxy of much of its interstellar gas. A galaxy is a massive gravitationally bound system consisting of Stars an Interstellar medium of gas and dust, and Dark matter Outer space, often simply called space, comprises the relatively empty regions of the Universe outside the escape velocities of Celestial bodies. [2]

The ram pressure increases when the velocity increases. For example, when you are in a windy place, you feel a force on your body from the wind. The stronger (faster) the wind, the greater the force you feel.
