Information

The drag force is dependent on the geometry and size of the object, the density of the air, the velocity of the object and the so-called Reynold's number. The calculation of the actual force is quite straightforward and can be seen in the text view of this component (press Ctrl+3). Look at the variable F_D to see the final force equation. The drag will be proportional to the velocity of the object through the air to the power of two.

The equations are taken from the book Physics for Game Programmers, written by Grant Palmer.
