The air pressure would be causing drag if it were placed against the face of the object, friction would be acting along its sides, and potentially a relatively negative pressure would be acting on its back or suction.
Air friction, or air drag, is an example of fluid friction. Unlike the standard model of surface friction, such friction forces are velocity dependent. The velocity dependence may be very complicated, and only special cases can be treated analytically.
20 Οκτ 2022 · Form drag, also known as pressure drag, is a significant component of aerodynamic drag in automotive design. It is caused by the motion of air around the vehicle, which leads to changes in air pressure. As the vehicle moves, the shape and frontal area of the vehicle cause the air to either compress or expand.
4 Μαρ 2017 · where D is the drag force, ρ is the air density, U is vehicle speed, and S is the frontal area. One of the nice aspects of this formula is that the coefficient doesn’t change much with speed, and it basically represents how smoothly the vehicle slices through the oncoming airstream.
Aerodynamic drag, sometimes called wind resistance, is an effect which a vehicle must overcome more and more as speed increases. Drag is a form of friction, though some of the air's effect on the vehicle is due to a low pressure zone behind the vehicle, and a high pressure zone in front.
Friction caused by air is called air resistance or drag. Bikes, cars and other moving objects experience air resistance as they move through the air.
The portion of the drag force that is due to the inertia of the fluid — the resistance that it has to being pushed aside — is called the pressure drag (or form drag or profile drag). This is usually what someone is referring to when they talk about drag.
