Do you agree with the statement friction is both good and evil explain with examples
Answers
Answer:
Friction is good because:-
1)It helps us to walk on a surface without slipping
2)It helps us to hold objects without them slipping out of our hands.
3)Grooved tires in vehicles helps to increase friction so that it gets a good grip on the road and not skid on the road
Friction is an evil because:-
1)It causes wear and tear in machine parts, shoes etc.
2)Heavy objects are difficult to push and pull because of friction present between the surface and the object
3)It decreases the speed of a moving object as it acts in the opposite direction to motion
Explanation
Thus friction is a necessary evil.
Hope you understood the answer.
Answer:
Yes,I agree with it.
Friction is both good and evil.
good side of friction:
If there is no friction we couldn't write with pen or pencil.
When our teacher is writting with chalk on blackboard , it's rough surface rubs off some chalk particles which stick to the black board.
If an object starts moving , it would never stop if there is no friction.
Without friction no building could be constructed.
EVIL SIDE OF FRICTION.
It wears out the material whether they are srews , ball bearings or soles of shoes.
Friction can produce heat.So, when a machine is operated , heat generated causes much wastage of energy.
