how is frictional force useful to us
Answers
Answer:
Friction can be useful. ... friction between our shoes and the floor stop us from slipping. friction between tyres and the road stop cars from skidding. friction between the brakes and wheel help bikes and cars to slow down.
Uses of Friction. Although you normally hear about trying to reduce or eliminate friction, it actually has some important uses. Since friction is a resistance force that slows down or prevents motion, it is necessary in many applications where you might want to hold items or do things and prevent slipping or sliding.
Without friction, a car is useless. However, friction can also cause problems in a car. Friction between moving engine parts increases their temperature and causes the parts to wear down. Friction can be both harmful and helpful, so it may be necessary to decrease or increase friction.
