```				   What is drag force?
```

7 years ago

```										Drag Force in a Medium

The force exerted on a body moving in a medium like air or water depends in a complex way upon the velocity of the body relative to the medium, the viscosity and density of the medium, the shape of the body, and the roughness of its surface.

The most common method of mathematically modeling the drag force is the equation,

FD
= Drag Force. SI: N

CD
= Drag Coefficient. SI: Dimensionless

A
= Coss-sectional Area perpendicular to the flow. SI: m2

r
= Density of the medium. SI: kg/m3

v
= Velocity of the body relative to the medium. SI: m/s

The direction of the drag force is always opposite the direction of the body's velocity.
