Question



Which one of the following is the correct increasing order of the rolling, static and sliding frictions?

A.

Rolling, static, sliding

B.

Rolling, sliding, static

C.

Static, sliding, rolling

D.

Sliding, static, rolling

Correct option is B


The correct answer is rolling, sliding, static.
· Rolling friction occurs when an object rolls over a surface. It is the smallest type of friction.
· Sliding friction is the resistance created when two objects slide against each other. It is greater than rolling friction but less than static friction.
· Static friction is the friction that keeps an object at rest when a force is applied. It is the greatest type of friction among the three.
· The correct increasing order of frictions is: Rolling, sliding, static.
Information Booster
· This order is based on the amount of resistance each type of friction offers: rolling friction offers the least resistance, followed by sliding friction, and static friction offers the most resistance.
Additional Information
· Coefficient of friction is a value that represents the ratio of the force of friction between two bodies and the force pressing them together.
· Kinetic friction is another term for sliding friction and occurs when two objects are moving relative to each other.
· Lubrication can significantly reduce both sliding and rolling friction by creating a thin layer between surfaces, thereby minimizing direct contact.
