FIND THE SITUATIONS IN WHICH FRICTION IS NON BENIFICIAL

1.	FIND THE SITUATIONS IN WHICH FRICTION IS NON BENIFICIAL
Answer» ~ 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.~ Forest fires are caused due to friction between BRANCHES of trees.~ Lot of effort and money goes in to techniques like oiling and greasing to overcome friction.~ Cause USUAL wear and tear of objects.
