Helo mate here your ans
we learn that THE IMPORTANCE OF FRICTION. Friction is an extremely important force to meteorology. Not only does friction decrease the wind speed, it also changes the direction of the wind. ... Since air molecules are free to move about, friction by viscosity is much less significant than friction between two surfaces.For example, friction between our shoes and the floor stop us from slipping and friction between tyres and the road stop cars from skidding. Friction is sometimes unhelpful. For example, if you don't lubricate your bike regularly with oil, the friction in the chain and axles increases.
