For streamlined bodies, frictional drag is the dominant source of air resistance. For a bluff body, the dominant source of drag is pressure drag. For a given frontal area and velocity, a streamlined ...

This is where the drag coefficient — which measures how well a vehicle cuts through the surrounding air — comes into play.

This slows the object down. Resistance in air and water is a type of frictional force that is also known as drag. Objects with a large surface area can produce more drag. The faster an object ...
