Hii dear,

● Laws of rolling friction-
1. Force of rolling friction is directly proportional to load and inversely proportional to radius of curvature.
F = μ×W/r

2. Rolling friction can be expressed in fractional power of load times constant.
F = kL^n
where k & n are experimentally determined.

3. Force of rolling friction is decreases with increase in smoothness.

Hope that was helpful...
