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.
fricton is useful in many many ways: help in protecting from slipping protect the car from sliding due to friction you can make fire from rubbing two stones. etc......... etc....
Enables cars to move, rather than just spin tyres and go nowhere.
Brakes are meant to have a lot of friction and it's useful.
It allows you to walk (with out friction between you and the floor this wouldn't be possible) It is needed for braking can be used to produce heat
Friction is useful in various ways, such as enabling us to walk and grip objects. It is crucial for vehicles to move on roads and for machines to operate effectively. Friction also helps in slowing down moving objects and preventing slipping or sliding.
No Friction Runes Computers
oil, graphite, grease
the friction from pushing the hull through the water is not useful as long as you're travelling.
It can be useful when a ball is catching
Friction allows us to walk without slipping by providing grip between our feet and the ground. It helps to slow down moving objects, such as vehicles coming to a stop on a road. Friction is essential for writing with a pencil, as it allows the graphite to leave marks on paper.
how does friction help car tyres?
Sandpaper is high in friction but is not considered useful in terms of being helpful in a general sense.
