Air resistance () is a force that affects objects that move through the air. It depends on the density of the air (), the area of the object (), the velocity it is moving (), and a "drag coefficient" () that accounts for other properties of the object like the surface roughness, and turbulence. Air resistance is also called "drag", and the unit for this force is Newtons (). Solve the equation below for .

F = pCDA/ 2 V2
