Question

Describe the factors on which the force of friction depends. ​

Answer 1

Answer:

The force of friction depends upon

1. The normal reaction force

2. The coefficient of friction

Explanation:

f= mew*N

mew= coefficient of friction(always given in question)

N= normal reaction force(equal to weight(mg) of the body)

Answer 2

Answer:

The force which opposes the motion of a body over another is called force of friction. The force of friction depends upon the following factors

(i) On a horizontal surface, the force of friction is directly proportional to the weight of the body which moves.

(ii) The force of friction depends on the nature of surface in contact.

For example, the force of friction between a pair of highly polished surfaces is very small as compared to the force of friction between two rough surfaces.

(iii) The force of friction does not depend upon the area of the surfaces in contact.
