What are the useful and harmful effect of friction?
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 is an example of not useful friction?
An example of not useful friction is the friction between the tires of a car and the road surface when trying to accelerate. This friction wastes energy in the form of heat and wears down both the tires and the road, without serving a beneficial purpose in this context.
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.
Two times when friction is useful?
Friction is useful in helping cars stop when brakes are applied, as the friction between the brake pads and the wheels slows down the vehicle. Friction is also beneficial in walking, as friction between the soles of shoes and the ground prevents slipping and provides traction.
Where can friction can be both useful and unwanted?
Friction can be useful in car brakes to slow down or stop a vehicle safely. On the other hand, friction can be unwanted between moving parts in machinery, as it can cause wear and reduce efficiency.

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
When is friction a useful force that acts between objects?
Most forms of conventional movement require friction. For example, a car could not go anywhere if not for the the friction between the rubber tire and the road surface.
What are the differences and similarities between Lincoln and Johnson?
This sight is very useful
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.
Where can friction can be both useful and unwanted?
Friction can be useful in car brakes to slow down or stop a vehicle safely. On the other hand, friction can be unwanted between moving parts in machinery, as it can cause wear and reduce efficiency.
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
