Expert Answer:

 

 

The force of rolling resistance can  be calculated by:

where

F is the rolling resistance force (shown in figure 1),
r is the wheel radius,
b is the rolling resistance coefficient or coefficient of rolling friction with dimension of length, and
Nf is the normal force, which is usuaaly equal to weight of the object. So above equation clarifies the relationship between rolling force and mass of body and radius of the body
