Drag is a force that opposes the motion of an object through the air. Things that affect drag are the shape of an object, the density of air and the speed of the object. Pressure Drag: Pressure drag, or air resistance, is the result of the push or pull of air against the shape of the object flying through the air. Friction Drag: Friction drag, or air friction, is a result of the contact and movement of air on an object moving through it. The amount of friction drag created depends largely on the amount of surface area on the object. .
