### Formula name

DRAG

### Description

Force of Drag

### Syntax

/*Force of drag experienced by an object surrounded by a fluid (liquid or gas)*/

/*A: the cross sectional area of the object

v: velocity of the object

C_w: drag coefficient

ρ: density of the surrounding fluid */

F = 1/2 *ρ* v^2 * C_w *A

/*A: the cross sectional area of the object

v: velocity of the object

C_w: drag coefficient

ρ: density of the surrounding fluid */

F = 1/2 *ρ* v^2 * C_w *A

### Notes

The force of drag depends of the shape of the object, its velocity, the density of the surrounding fluid and the drag coefficient. In most cases the drag coefficient is obtained from experiments.
