Just think if friction could not be obtained; your alternator would not charge the battery because the belt slips on the pulley. A car with a clutch would not move because the clutch slips. Friction is advantageous and desirable for some things and not for others. If we could eliminate friction, you would not need much gas to propel your car down the road. If you could not achieve friction with your lover, you would not achieve orgasm.
Machines are useful for all kinds of things. Machines can give you a break from using your hands.
Friction converts mechanical energy into heat, which is rarely useful, and which can never be recovered in its entirety. Due to conservation of energy, this heat energy is not available for other things, i.e., for useful work.
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.
Brakes are meant to have a lot of friction and it's useful.
yes friction is very useful because it help objects not to slide or slip
stopping cars Friction is useful to start a fire with sticks.
