Question

on what factors does the force of friction depends on? explain with examples

Answer 1

The force of friction depends upon the factors like
1)mass of object
2)nature of surface
e.g.
if the mass of an object is increase the force of friction also increases and on roughy surface force of friction is much more as compared to smooth surface
mark me as brailiest

Answer 2

The force of friction depends upon the following factors:

• The force of friction depends upon the nature of the surface which is in the contact. For example, While walking on a rough surface, the force of friction is more, While climbing the mountain the friction is increased by wearing special types of shoes to increase friction.
• When we rub our hands, sliding friction comes into play as the surface is rough.
• The force of friction is directly proportional to the mass of the object. For Example, When a heavy vehicle is moving on a road, it has more force of friction than light vehicles.
