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
Friction is useful because it helps objects grip surfaces, allowing us to walk, drive, and hold objects. However, friction can also cause wear and tear on surfaces, leading to damage over time. Excessive friction can also generate heat, which can be harmful in certain situations, such as in machinery.
Useful friction is beneficial because it allows us to walk, drive or grip objects. Harmful friction, on the other hand, can lead to wear and tear on surfaces, reduce efficiency, and cause overheating in machinery. Helpful friction can be controlled and optimized for various purposes, while harmful friction needs to be minimized to prevent damage.
Positive effects of friction include providing grip for tires on the road and allowing us to walk without slipping. Negative effects include wearing down of machinery parts over time and causing heat generation which can lead to wear and tear.
Ice on a flat surface - low friction but not useful for walking safely Greasy surfaces - low friction but not useful for handling objects securely Wet banana peel - low friction but not useful for maintaining balance
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.
stopping cars Friction is useful to start a fire with sticks.

lion are useful and harmful
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.
It is not harmful. Also it is not useful
Brakes are meant to have a lot of friction and it's useful.
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
Ozone in stratosphere helps to absorb the UV rays. These are the harmful rays of the sun.
friction can be harmful because if you stick 2 objects to rub against eachother for to long it will explode
