The coordination of fine motor skills in my hand and fingers allows me to hold and maneuver the pencil. The brain sends signals to control these movements, enabling me to make precise marks on paper. Additionally, the pencil's graphite core leaves a trail of particles as it is dragged across the paper, creating the written text.

Does a pencil need friction to write?
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.
Is it true pencils do not need friction to write?
No, pencils do require friction to write. When a pencil is pressed against paper, the friction between the graphite tip and the paper surface causes the graphite to leave a mark. Without this friction, the pencil would not be able to write.
Do pencils need friction to write with?
Yes, pencils need friction in order to write. The friction between the pencil lead and the surface of the paper allows the lead to leave a mark as it rubs off onto the paper. Without friction, the pencil lead would not be able to transfer onto the paper.
Why should you never use a dull pencil?
Using a dull pencil can make writing or drawing more difficult and reduce the quality of the final product. It can also lead to smudging and uneven lines. Additionally, a dull pencil can cause hand fatigue as you need to exert more pressure to make marks.
How come you can stick a pencil through a balloon without popping it?
When you stick a pencil through a balloon slowly, you are able to stretch the balloon material around the pencil, creating a seal that holds the air inside. The pressure of the air inside the balloon forces the balloon material to seal around the pencil, preventing it from popping.
