Answer 2

Disadvantages of Friction:

• 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.

• Forest fires are caused due to the friction between tree branches.

A lot of money goes into preventing friction and the usual wear and tear caused by it by using techniques like greasing and oiling.
