What do you mean by the term friction ? State the factors on which it depends ?
Dear Student,
Friction is the force that opposes the motion of one body sliding over another or we can say which provide hindrance in a motion.
Why friction is existing almost everywhere is because the surfaces may appear to be smooth, however, on a microscopic scale the surfaces are pitted and jagged. When another similar surface is in contact with it, the irregularities and peaks interlock.

The friction force depends on two factors:
- a) Materials- Rougher surfaces have a higher coefficient of frictions.
- b) The force- Pushing the surfaces together increases the surface area in contact with each other which increases friction.
