in some cases, we deliberately increase friction . explain why?? plz answer this question fast........

Answer»

Explanation:

We deliberately INCREASE FRICTION by using brake pads in the brake system of bicycles and automobiles. When we are RIDING a bicycle, the brake pads do not touch the wheels. But when we PRESS the brake lever, these pads arrest the motion of the rim due to friction.
