Question

Which of the following statements is incorrect ?
A. static friction is greater than rolling friction
B. sliding friction is less than rolling friction
C. rolling friction is less than static friction
D. static friction is greater than sliding friction

Answer 1

Answer:

B. sliding friction is less than rolling friction is the incorrect option.

Answer 2

B. sliding friction is less than rolling friction

Explanation:

Friction is a phenomenon which resists motion when an object is rubbed against another. Static friction is between two objects that are not moving. Sliding friction is between two objects when one or both are sliding against each other. Sliding friction is lesser than static friction. Rolling friction is between two objects where one or both of the surface is circular. Rolling friction is less than sliding friction.

Static > Sliding > Rolling

Option B is the answer
