Friction and velocity
WebMar 14, 2024 · With Friction. When the velocity of the object is more than the optimal velocity, the object will be prone to sliding up the incline; so the force of friction (which always opposes the direction ... WebSep 12, 2024 · Like friction, the drag force always opposes the motion of an object. Unlike simple friction, the drag force is proportional to some function of the velocity of the object in that fluid. This functionality is complicated and depends upon the shape of the object, its size, its velocity, and the fluid it is in.
