why does rolling friction create lesser friction compared to the force created while sliding or dragging?

Expert Answer:

- When an object rolls over the surface of another object, the resistance to its motion is called rolling friction. 
- It easier to roll an object than to slide an object.
- Thus, rolling friction is much less than sliding friction.
