As an object (I will use a ball for an example) slides across a surface or terrain it will gradually heat up and slow down due to the composition and features on the surface. Such features include coarseness/roughness. Friction is described in Newtons Three Laws of motion.
Considering the work input and output distance, to account for the effect of friction, the output force must be greater than the input force due to the work lost to friction. This means that the output force required to move the object the specified distance against friction will be higher than what would be calculated based solely on the given work input and output distance.
The force of friction needs to touch an object to have an effect. Friction occurs when two surfaces are in contact and one surface resists the motion of the other surface. It is this resistance that allows friction to have an effect on objects in contact.
The formula for calculating the work done by friction is: Work Force of friction x Distance.
The desirable effect of friction is that it allows us to walk, drive, and grip objects without slipping. This type of friction also helps us stop moving objects and control their speed.
No, more friction does not necessarily mean more work. Friction is a force that resists motion, but work is defined as the product of force and displacement in the direction of the force. So, while friction can make it harder to do work in certain situations, they are not directly proportional.
it rubs the steel because its friction!

No, We cannot do work on friction less surface
Friction slows down objects by in some capacity rubbing against them
yes
Friction is independent of speed once an object is moving since faster does not mean more friction.
work is movement, and all movement causes friction, since there is no such thing as a "perfect" or "100% efficient" tool yet.
