3. Both 1 and 2

4. None of the above

The ratio of the frictional force resisting the motion of two surfaces in contact to the normal force pressing the two surfaces together is called the Coefficient of friction. It is denoted by μ. It is a dimensionless quantity.

Table of content ## Answer: The coefficient of friction depends upon the nature of the surface.

It has different values for static friction and kinetic friction. The phenomenon in which the frictional force resists force that is applied to an object is called static friction. In this, the object remains at rest until the force of static friction is overcome. Kinetic friction refers to the frictional force resisting the motion of an object.

### More details on the Coefficient of friction

Following are the crucial details related to the Coefficient of friction :

• It is the measure of the amount of friction existing between two surfaces.

• It may be adjusted upward or downward by the use of fillers.

• It is one of the key parameters to analyze the tribological characteristics of the tested fuels.

• It shows the relationship between two objects and the normal reaction between the objects that are involved.

• It depends on the objects that are causing friction.

Summary:

## Coefficient of friction depends upon

Out of the given options, the Coefficient of friction depends upon nature of surface. GradeStack Learning Pvt. Ltd.Windsor IT Park, Tower - A, 2nd Floor, Sector 125, Noida, Uttar Pradesh 201303 help@byjusexamprep.com
