explain friction in both the ways as a good and as a evil ??
Answers
Answer:
Yes, friction is both good and bad.
Friction is advantageous:
1. While walking as without friction it would be difficult for us to step on the ground
2. In the movement of vehicles on road.
3. In holding a pencil while writing.
Friction is disadvantageous:
1. As more work is to be done while movement of an object.
2. Due to friction, there will be wear in machines. As a result, their life and efficiency get reduced.
Yes I agree with that statement.
Friction is good:-
*It is due to friction between our foot and ground,that helps to walk properly
*It is due to friction between our fingers and the pen,that helps us to hold it properly
*It is due to the presence of friction between the tyres of a car and the ground that helps us to drive a car
Friction is bad:-
*If there was no friction we don't need to pedal the cycle continuously
*If there was no friction we can easily push or pull furniture and other things
