WebDrag coefficient(Cd) is a commonly published rating of a car's aerodynamic smoothness, related to the shape of the car. Multiplying Cdby the car's frontal area gives an index of total drag. The result is called drag area, and is listed below for several cars. The width and height of curvy cars lead to gross overestimation of frontal area. WebIn ballistics, the ballistic coefficient ( BC) of a bullet is a measure of its ability to overcome air resistance in flight. A high BC means the object will slow down less. It will have more of its speed left when it reaches the …
