Question

write about the Rolling fractional ​

Answer 1

Explanation:

Rolling friction is expressed as a product of load and constant to the fractional power. Rolling friction force is directly proportional to load and inversely proportional to radius of curvature.

The other type of friction is Sliding friction. In this type of friction, there is a restriction on the body’s movement as only one side of the body is in contact with the surface. Pushing a box across the table is an example of Sliding friction. Rolling friction is considerably weaker than Sliding friction

This constant ratio is called the coefficient of friction and is usually symbolized by the Greek letter mu (μ). Mathematically, μ = F/L. Because both friction and load are measured in units of force (such as pounds or newtons), the coefficient of friction is dimensionless.
