Detailed Solution
Download Solution PDFThe correct answer is Rolling, sliding, static.
Key Points
- 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.
- 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.
