Answer:in many situations friction needs to be increased. 1) By making the moving surfaces rough : Tyres of vehicles have designed with grooves on the surface to increase friction. A large friction provides a better grip to vehicles on the road and prevents them from skidding.
Explanation:
Sometimes friction between two surfaces decreases to such an extent that it is difficult to move on that surface. So, friction needs to be increased. ... Here the increased friction reduces the speed at which your tires are turning. The relatively constant friction between the tires and the road then slows the car down
