WebWithout friction, they would not be able to accelerate, turn or brake. Friction can also be unhelpful. For example when the mechanical parts of a bike, like the chain and axles, rub … WebFriction. An object will not move initially due to static friction. Static friction (Fs) is the force exerted on a stationary object by a surface that prevents the object from starting to move. The applied force must be large enough to …
