__Rolling Friction Formula:__

Rolling Friction occurs when a wheel, ball, or cylinder rolls over a surface, as opposed to sliding friction.

It is the force resisting the motion when a body rolls on a surface, mainly due to deformations caused at the contact area between the body and the surface.

This type of friction is essential in fields like automotive engineering, manufacturing, and robotics because it affects the efficiency and wear of moving parts.

Rolling friction is generally lower than sliding friction, making it crucial in designing vehicles and other wheeled machinery to optimize performance and reduce energy consumption.

Rolling friction, F_{roll(N)} in Newtons is equal to the product of rolling resistance coefficient, C_{rr} and normal force, N_{(N)} in Newtons, N.

Rolling friction, F_{roll(N)} = C_{rr} * N_{(N)}

F_{roll(N)} = rolling friction in Newtons, N.

C_{rr} = rolling resistence coefficient.

N_{(N)} = normal force in Newtons, N.

- Calculate the rolling friction for a car tire:

Given:

- Coefficient of rolling resistance, Crr = 0.03
- Normal force (weight supported by the tire), N
_{(N)}= 3000 N

**Rolling friction, F _{roll(N)} = C_{rr} * N_{(N)}**

**F _{roll(N)} = 0.03 * 3000**

**F _{roll(N)} = 90N.**

- Determine the total rolling friction for a four-wheeled wagon:

Given:

- Coefficient of rolling resistance, Crr = 0.015
**Rolling friction, F**3 N_{roll(N)}=

**Rolling friction, F _{roll(N)} = C_{rr} * N_{(N)}**

N_{(N)} = **F _{roll(N)} / C_{rr}**

N_{(N)} = 3 / 0.015

N_{(N)} = 200N.
