Detailed Solution

The above statement is true.
The main difference between Rolling Friction and Sliding Friction is that Sliding Friction happens when one surface rubs against another surface, whereas Rolling Friction happens when a body rolls over another surface.
Rolling friction takes place when an object rolls on another surface. Sliding friction occurs when an object slides over another surface with a working fluid between the two bodies. Sliding friction is greater than rolling friction. It is because, during sliding friction, the area of interaction between both surfaces will be less compared to sliding friction. In sliding friction, the interlocking of molecules will be high, which results in high frictional force between the bodies.
