| drag |
For a solid object moving through a fluid or gas, drag is the sum of all the aerodynamic or hydrodynamic forces in the direction of the external fluid flow. It therefore acts to oppose the motion of the object, and in a powered vehicle it is overcome by thrust. Types of drag are generally divided into two categories: parasitic drag and lift-induced drag. Parasitic drag includes form drag, skin friction and interference drag. ...
