Can anyone list 10 advantages and disadvantages of friction ?
Advantages of friction:
-
Friction helps us to walk on the ground
-
We can write on a paper or on a board due to friction
-
Friction helps in stopping a vehicle on applying the brakes.
-
It helps in generating heat when we rub our hands together
-
Asteroids burn in the atmosphere before reaching the earth due to friction and saves lives on earth.
Disadvantages of friction:
-
Friction produces a lot of heat in various parts of the machinery and this leads to wastage of energy as heat
-
Opposes motion, hence more energy is needed to overcome friction
-
Noise production in machines is irritating as well as leads to energy loss
-
Forest fires are caused due to friction between branches of trees
-
Lot of effort and money goes in using techniques like greasing and oiling to overcome friction and usual wear and tear caused by it
