Definition of drag force in physics
WebThe law, first set forth by the British scientist Sir George G. Stokes in 1851, is derived by consideration of the forces acting on a particular particle as it sinks through a liquid column under the influence of gravity. In Stokes’s law, the drag force F acting upward in resistance to the fall is equal to 6 πrηv, in which r is the radius ... WebA drag force is the resistance force caused by the motion of a body through a fluid, such as water or air. A drag force acts opposite to the direction of the oncoming flow velocity. …

Form drag is similar to the. normal force. provided by the … WebJul 27, 2024 · F = (m dot * V)e – (m dot * V)0. The first term on the right hand side of this equation is usually called the gross thrust of the engine, while the second term is called the ram drag. It is a drag term because it is subtracted from the gross thrust. Since the exit mass flow rate is nearly equal to the free stream mass flow rate, and the free ...
