Question

give examples to show that friction in both a friend and a foe​

Answer 1

Answer:

Friend:

Without friction we wouldn't be able to write

Without friction we wouldn't be able to walk

Foe:

Friction causes wear and tear in objects

It reduces speed up moving objects so more force is required

Answer 2

yes , friction is a friend as well as foe.

Friction is an opposing force that comes into play when one body actually moves (slides or rolls ) or even tries to move over rhe surface of another body.

Thus, force of friction is the force that develops at the surface of contact of two bodies and impedes (opposes) their relative motion.

friction as a foe

• roughness of surfaces is the cause of friction.
• roughness of surfaces is the cause of friction.The irregularities are formed of projections and depression

Friction as a friend

• It arises an account of strong atomic or molecular forces of attraction between the two surfaces at the points of actual contact.
• It arises an account of strong atomic or molecular forces of attraction between the two surfaces at the points of actual contact.it also creates the force of adhesion.
