Heat
sliding around, a little bit of movement. no movement.
Friction
A high coefficient of friction may be caused by a rough surface. It may also be the result of surfaces sticking together, as in the case of rubber which tends to stick to certain surfaces, at least when it is dry. Lubrication - such as a thin layer of oil - tends to reduce the coefficient of friction.
Yes, friction exists whenever two objects touch. Friction is caused by two effects: direct contact of mechanical surface irregularities and the electromagnetic force. It has nothing at all to do with the gravitational force, the strong force, or the weak force.

Friction is a result of the interactions between surfaces that are in contact, more precisely, it arises from microscopic interactions between jagged natures of surfaces. Friction is present even when an item is not moving.
newtons are a measurement of mass and friction is the result of two surfaces rubbing together to usually create heat

Metals often wear each other away as a result of friction between adjoining surfaces.

Two surfaces touching together creates friction. rub your hands together(two surface from your each hand) creates friction and head is the result.
Generally, friction is the result of the resistance between two or more moving surfaces. Also speaking generally, there are no moving parts in the brain, and movement in the brainpan is not a good thing. So, all things being normal, there is no friction in the brain.
Because the 'creak' is the result of friction generated by the hinge parts moving. Grease or oil deposits a thin film of lubricant between the surfaces, preventing friction (and thus the creak) happening.
Pulling a sled across a sidewalk because rougher surfaces have more friction.
