WebIn fluid dynamics, drag (sometimes called fluid resistance) is a force acting opposite to the relative motion of any object moving with respect to a surrounding fluid. This can exist between two fluid layers (or surfaces) or between a fluid and a solid surface.. Unlike other resistive forces, such as dry friction, which are nearly independent of velocity, the drag … Web23 de jun. de 2009 · It increases. Static friction is the friction that opposes an object at rest to begin moving, given the following formula :- Fs = MsN, where ms is the coefficient of …
