Question

Write any two advantage and disadvantages of friction​

Answer 1

Friction produces unnecessary heat leading to the wastage of energy. The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects.. A lot of money goes into preventing friction and the usual wear and tear caused by it by using techniques like greasing and oiling.

Answer 2

Answer:

Advantages of Friction:

•Friction is responsible for many types of motion.

•It helps us walk on the ground.

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.
