Question

what is friction ? write its advantages ​

Answer 1

Answer:

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Advantages of Friction:

Friction is responsible for many types of motion. It helps us walk on the ground. ... Asteroids are burnt in the atmosphere before reaching Earth due to friction. It helps in the generation of heat when we rub our hands.

Answer 2

Explanation:

It is the force which provides resistance to motion of solid objects.
