Question

17. Describe the disadvantages of friction.​

Answer 1

Answer:

Hope this helps you

Explanation:

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.

Answer 2

$\small\mathbf\orange{{Disadvantages \: of \: Friction : }}$

• 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.
• 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.
