Question

define friction.............​

Answer 1

Answer:

friction : when a body moves or tends to move on the surface of the other body , a force comes into play which is opposite to the motion of the body that force is called friction

Answer 2

Answer:

Friction is a force which slows down the movement of objects sliding over each other or rubbing against each other.

->Friction acts against or resist movement.

-> Two rough surfaces cause more friction than two smooth surfaces.

-> Friction occurs because there is no surface which is perfectly smooth.

-> The soles of the shoe, three of cycles and motors have a pattern if grooves which allows the water to escape from the shoes and wheels.

-> We cannot walk with slippers on very smooth and wet surfaces due to very less friction.

Hope it helps
