A body moving through a fluid experiences a drag force, which is usually divided into two components: frictional drag, and pressure drag. Frictional drag comes from friction between the fluid and the ...

As the bicycle and its rider move along the road, the air exerts a force that increases sharply with speed. The force is due to friction between the air and the exposed surfaces of the rider and ...

This video is all about the drag force. There are two main causes of drag - first we have the pressure distribution around the object, which is particularly significant if flow separation occurs.
