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.
When is friction greatest?
Friction is greatest in the absent of lubrication. This happens when two objects rub against each other and this might be useful or harmful depending on the set up.
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.
Is friction useful?
yes friction is very useful because it help objects not to slide or slip
Is one way that friction is useful?
stopping cars Friction is useful to start a fire with sticks.
Is oxygen is the harmful or useful gas?
That depends on what effect is desired; If you like to breathe, it is a useful gas; If you prefer that your car (or whatever) not be rusty (oxidized), then it is a harmful gas.

Can friction be harmful and how?
Yes, friction CAN be harmful, depending on where it occurs. If you'd fall and scrub your knee, that's harmful friction. IF your shoes are chafing and yopu get a blister, that's harmful friction. In a machine, if a bearing becomes warm, that's harmful friction.

Describe 3 examples where low friction is not useful?
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.
Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
What are Useful and Harmful Changes?
The changes talking place in our surroundings and which are useful to us are called Useful changes. The changes which are not useful but harmful are called Harmful changes
What useful effect does ozone have in the stratosphere?
Ozone in stratosphere helps to absorb the UV rays. These are the harmful rays of the sun.
How can friction can be harmful?
friction can be harmful because if you stick 2 objects to rub against eachother for to long it will explode
