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.

What are the differences between useful and harmful friction?
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.
Negative and positive effects of friction?
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.
List some low friction and not useful?
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
What is high in friction but is not useful?

Are lions harmful or useful?
lion are useful and harmful
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.
Is a ameoba harmful or useful?
It is not harmful. Also it is not useful
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
