Question

Rolling friction is less than sliding friction. a. True b. False

Answer 1

Answer:

The given statement is TRUE

Explanation:

Friction is a force experienced by a body that resists its motion.

In other words, Friction is the force experienced by the two bodies (with uneven or rough surfaces) when moving against each other.

When an object slides on a surface, the surface area of the object in contact with the surface is more as compared to an object which is rolled on the surface. Therefore, the friction force experienced by the sliding body is greater than the rolling body.

Therefore, we can say that the rolling friction is less than the sliding friction.
