Useful effect of friction - automotive clutch , friction material on adjacent plates help give grip the other plate connected to drive shaft , hence allowing the friction to slowly bring the drive shaft up to speed , otherwise the motor would just stall.
Or to give useful grip to tyres on the road.
Harmful effect of friction - makes bearing harder to turn since friction holds on to surface between the bearing and the bearings outer surface

What are the differences between useful and harmful friction?
The type of friction that benefits in some or other way like smooth running of vehicles on the road is called Useful Friction whereas other wherein it becomes a causative factor for wear and tear or damage to the object in question.
Negative and positive effects of friction?
friction can cause: 1) Physical wear and tear of moving parts. 2) degradation of materials by continuous friction. 3) wastage of 70% of energy in car engines. However, friction is useful in: 1) walking 2) car brakes, friction between brake pads and Tyre causes car to slow down. 3) techniques like friction welding.
What is high in friction but is not useful?

Where friction is useful or nuisance for us?
Lots of friction in the world, some useful, some harmful. But friction is not something that merely exists or does not. It can be measured, and a thing can be said to have too little, too much, or a good amount. If you get a rope burn, when a rope you are holding slips in your hands, that is harmful friction. Friction causes a car to stop when the breaks are put on. An ice skater uses skates because they get traction with their sharp edges, but there is low friction on the blade to slide on the ice. If you were on a roof made of asphalt tiles, and the roof were not too steep, it would be friction that holds you in place. You would know better than to go on the roof if it were covered by ice, because the friction would be too low - it would be slippery.
