Question

Which of the following is not a type of friction?

• A. static friction
• B. rolling friction
• C. sliding friction
• D. slow friction

Answer 1

The correct option is D

slow friction

1. Static friction, rolling friction, and sliding friction all are types of friction.
2. Static friction acts on an object when the object is at the rest condition.
3. Rolling friction acts on an object when the surface of an object rolls on the surface of another object.
4. Sliding friction acts on an object when the surface of any object slides over the surface of another object.
5. Hence there is no slow friction as a type of friction.

Hence, (d) is the correct option.
