Question
does writing with a pencil include sliding friction or air resistance or rolling friction
Answers

When writing with a pencil, the primary type of friction involved is sliding friction (also known as kinetic friction). This occurs between the pencil tip and the paper as the pencil glides across the surface while writing.
Air resistance (also known as drag) is generally negligible when writing with a pencil because the motion is relatively slow and the surfaces in contact (the pencil and paper) are not moving through air in a way that generates significant drag.
Rolling friction is not typically a factor in writing with a pencil, as the pencil does not roll in the same way a wheel or ball does. The tip of the pencil stays in contact with the paper and slides to create marks.
In summary, the main type of friction involved when writing with a pencil is sliding friction.
