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 … WebAs the relative velocity approaches the speed of light, γ → ∞. Time dilation (different times t and t' at the same position x in same inertial frame) Derivation of time dilation In this example the time measured in the frame on the vehicle, t, is known as the proper time.
