Gears are not perfect example for rolling friction. Most energy lost in gear operation is due to the surface shear stress, which is more like sliding friction. Rolling friction is due to the pressure induced torque applied on the roll axis. Under this circumstance, the equivalent pressure force doesn't point to the roll axis, which creates a torque to resist the rolling motion. A good example for rolling friction can be a running wheel of the car.

How is rolling friction caused?
How is rolling friction caused
What are the three types of friction and when does each apply?
There are three types of friction, static friction, rolling friction, and sliding friction. Static friction is friction between two surfaces that aren't moving relatively to each other. Rolling friction is friction between a rolling object and the surface that it is rolling on. Sliding friction is friction where an object slides, or rubs against, another surface.
Why is rolling friction is lesser than sliding friction?
due to the less surface area rolling friction is lesser than sliding friction
What forces act on a rolling ball?
It acts as a rolling friction or rolling resistance when it starts to roll on a flat surface , it resists the direction of rotation of the object in both clock wise and anti clock wise direction.
What is the strongest type of friction?
There are four types of friction: Fluid Friction (The friction caused by falling through air or water, or any other liquid etc), rolling friction (Like a ball rolling across the floor), static friction (The force it takes to begin something's movement), and sliding friction(Like pushing a box across the floor). In order of strongest to weakest it's Static, Sliding, Rolling, Fluid.
Tell you some apllications of rolling friction?
A wheel is an example of rolling friction. An example of rolling friction would be if you took kyle leary and folled him down a hill. his fat touching the grond would create rolling friction
What is one example of rolling friction?
rolling paper becuse it produce kinetic friction and kinetic energy
What is one example of rolling kinetic friction?
Anything with wheels, such as a car, would be an example of use of rolling kinetic friction.
4 types of friction and give an example of each?
Rolling Friction, Static Friction, Sliding Friction, & fluid Friction
Is a boat sailing on the ocean is an example of rolling friction?
No, it is not. Rolling friction occurs when a round object rolls across a surface. A boat on the ocean is not in contact with any solid surface. Instead of rolling friction the boat is subject to drag.
How is rolling friction caused?

What are sources of friction?
Driving a car down the street is a source of friction. Rolling a bowling ball down the lane is also an example of friction.
What is bad friction in gears?
bad friction is when 2 things rub together .
Which friction has least value option sliding friction static friction rolling friction Air friction?
i think it it rolling friction
Is the limiting friction is always less then rolling friction?
no limiting friction is not less than rolling friction

Rolling friction is friction between a rolling object and the surface that it is rolling on. Sliding friction is friction where an object slides, or rubs against, another surface.
What is the Direction of friction for a rolling body?
The direction of friction of a rolling body is in opposite direction to the motion of the rolling body.
