Because it's friction that rubs the graphite off the pencil on to the paper to make the words you write.
Writing with a pencil is an example of kinetic friction. This type of friction occurs between two surfaces in relative motion, such as the pencil tip and the paper, which creates heat and wears down the pencil lead over time.
Static friction is the type of friction used when writing with a pencil. As the pencil moves across the paper, static friction between the pencil tip and the paper surface enables the pencil to grip and leave a mark.
your using the force called muscular force.
The sound you hear when using a pencil sharpener is due to the friction created as the blade shaves off the wood and graphite from the pencil. This friction causes vibrations in the pencil sharpener, which produce the sound. If the pencil sharpener is making a loud or unusual noise, it may be a sign that the blade needs to be cleaned or replaced.
Yes, a pencil needs friction to write. When you apply pressure to the pencil against the paper, the friction between the graphite tip and the paper creates the marks. Without sufficient friction, the pencil would not be able to leave a mark on the surface.

Mechanical energy is converted into sound and heat energy when using a pencil sharpener. The mechanical energy from turning the handle is used to rotate the blade, which grinds the pencil lead to create a sharp tip. The sound comes from the friction between the blade and the pencil, while heat is generated from the friction between the blade and the pencil shavings.
Friction is useful for a pencil when writing or drawing as it creates the necessary resistance between the pencil tip and the paper to leave a mark. This friction helps transfer the graphite or ink from the pencil onto the surface, allowing for clear and precise writing or drawing.
Anything with wheels, such as a car, would be an example of use of rolling kinetic friction.
Friction
A pencil is erasable, a permanent marker pen is not.
The friction created when writing with a pencil is primarily kinetic friction. As the pencil moves across the paper, the tiny irregularities in the paper and pencil lead create resistance that enables the pencil to leave a mark.
