When you drive a car and stop it is because of friction you stopped. If there was no friction your car won't stop and will slide. Friction also helps with waking, if there was no friction with every step you take you would slip. Friction lets your foot stay in one spot while you move the other foot. Ice has no friction so it is hard to walk on and hard to brake on (if driving a car.)
Friction is not useful in situations where smooth movement or sliding is required, such as in lubricated machinery or in sports like ice skating. Additionally, in situations where reducing wear and tear is important, such as in engine components, friction is detrimental.

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?
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.
Is one way that friction is useful?
stopping cars Friction is useful to start a fire with sticks.
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.
Is friction useful when are going down a slide?
Friction can be useful to control the speed of the slide and prevent the person from sliding too fast. However, too much friction can cause the person to come to a sudden stop or experience discomfort. Finding the right balance of friction is important for a smooth and enjoyable slide experience.
What is useful friction?
there is friction in your cars brake system and without that frictiuon there your car would roll away whenever it was on a hill so this is a good example of when friction is useful.
What are some ways that friction is useful?
Friction can be useful for stopping cars when the brakes are put on, if you're running and need to stop quick, so basically to get grip. Also friction is good for fires and warmth.
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.
