Define the force of friction. list the factors affecting the force of friction. explain with example

Answered by admin @ 20/08/2021

Answer:

The force that opposes any motion between 2 object that are in contact with each other is called friction. Ex. A ball rolling on the ground.

Factors affecting the force of friction are:-

1. Nature of the 2 surface in contact.

The force of friction is less if the surface is smooth and if the surface is rough,force of friction is more. Eg, sprinkling talcum powder on carrom board, the friction between the striker and the board is very much reduce.

2. Force pressing the 2 surface together.

Friction arises due to interlocking of irregulating between 2 surface in contact and it increases with increase in force pressing the surface as lighter object having lesser weight applied less pressing force. Hence, it's easier to push a lighter lighter box than the heavier one.
