In physics, ram pressure is a pressure exerted on a body which is moving through a fluid medium.

In May, when the solar wind died down, there was a sudden drop in the ram pressure compressing the magnetosphere.

A bell-mouth inlet duct is extremely efficient, and is used where there is little ram pressure available to force the air into the engine.

Pitot sensors are used to measure ram pressure, which is added to static pressure to derive the airspeed of an aircraft.

--it plunged as though oblivious to the ram pressure of air.

At this altitude the spacecraft encountered sufficient ram pressure to raise temperatures on the solar arrays to 126-degrees Celsius.

Their collective ram pressure agonizingly pushed against the bow shock.

It is designed to be as efficient as possible at recovering the ram pressure of the air stream tube approaching the intake.

Some models also rely on ram pressure stripping as a shaping mechanism.

In contrast, ram pressure stripping mostly affects the Large Magellanic Cloud, because it has a larger reservoir of gas.
