Question

State whether the given statement is true or false :

Friction is necessary to perform many tasks.

• A. True
• B. False

Answer 1

The correct option is A True

Friction helps to lock the two surfaces in contact.

However, if there was no friction, we would not be able to perform even simple tasks like writing on a paper, or fixing a nail in the wall, stopping or turning an automobile, or even something as simple as tying a lace knot. However, in some cases it is desirable to reduce friction but it can never be eliminated.
