What type of friction is the frictional force needed to start on object at rest into motion?

Static


How the friction is called somewhat evil in our life?

Because it takes all the F=μN out of our lives! F- Force in Newtons (N) μ - Greek letter Mu (Coefficient of friction with no units) N-Normal force (force perpendicular to surface measured in newtons N) (found using mass * gravity assuming you're on a flat surface) When a surface has a lot of friction, the force applied is lowered due to the higher friction coefficient. When there's more friction, it takes more force to move an object on a surface.

What is the force called the resists the movement of one surface past another surface called?

I'm not sure if you are talking about friction or not. Does this force produce heat? Friction, I think


What is the friction that exits between a surface sliding on another surface is called?

If the two surfaces are moving relative to each other, then the friction between them is Kinetic Friction. Prior to the surfaces moving there was Static Friction between them.

false it is rolling friction
