li.Define friction? What are the factors affecting friction? Explain with examples.

Answer»

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.Lubrication present within any surface is on of the causes that affect the phenomenon of friction.

Also, the texture of the surface on which friction is taking place also affects friction.

Instance for such an occurrence, adding oil on a surface as a method of lubrication will affect the degree of friction to a great extent, turning it much smoother.
