when a roller is rolling on a flat surface with a constant speed, how is about the friction force?
is there any friction forces or not?

Curl said:constant speed doesn't say much - it could be a forced motion.
Have you rolled a marble along a flat surface? What about trying different flat surfaces?hokhani said:when a roller is rolling on a flat surface with a constant speed, how is about the friction force?

I'm guessing your thinking of rolling resistance, as opposed to static friction. Wiki article about rolling resistance:hokhani said:when a roller is rolling on a flat surface with a constant speed, how is about the friction force?
Friction is a force that resists the motion of objects in contact with each other. It is caused by the irregularities in the surfaces of objects that interact with each other.
The force of friction can be calculated using the equation F = μN, where μ is the coefficient of friction and N is the normal force between the two surfaces.
Rolling friction is a type of friction that occurs when an object rolls over a surface. It is typically less than sliding friction because there is less surface area in contact.
Rolling friction occurs when an object rolls over a surface, while sliding friction occurs when two surfaces slide against each other. Rolling friction is typically less than sliding friction because there is less surface area in contact.
At a constant speed, the force of friction is equal to the force applied to the object in motion. This means that the object will continue to move at a constant speed, with the force of friction balancing out the applied force.
