When you erase a pencil mark, you are observing the effects of friction between the eraser and the paper. Friction is the force that resists the motion of two surfaces sliding against each other. As you move the eraser back and forth over the pencil mark, the friction between the eraser and the paper causes the graphite particles from the pencil mark to stick to the eraser and be lifted off the paper. This process demonstrates how friction can be used to remove unwanted marks or materials from a surface.

What type of kinetic friction is used to write with a pencil?
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.
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.
When can friction be useful for a pencil?
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.
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.
What type of FRICTION is created when you write with a pencil?
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.
Can a pencil marking erase more than a color pencil?
if you have a good eraser yes. a good eraser will erase a lot of the colored pencil, but it will erase all of the normal pencil. it also depends on how dark the mark is.
What is rubber made for?
at first the rubber is made to erase the pencil mark.

How Can you leave scars on your wrists without cutting?
You can, like, with a pencil. Just do it hard enough, and it will mark. Just erase the pencil later on. And you can snap a rubber band onto the wrist. it will mark.
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.

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.
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.
How is friction important in writing?
Friction provides resistance between the writing surface and the pencil lead, allowing for control and precision when writing. It helps to create frictional force required for the pencil to mark the paper, making the writing process possible.
How does pencil work?
A pencil works by transferring graphite material onto a surface as you write or draw. The graphite leaves a mark on the surface due to friction and pressure applied by the pencil tip, allowing you to create text or images.
Why is it difficult to write on glass with a pencil?
Glass is a hard and smooth surface, making it difficult for the pencil to leave a visible mark. The graphite in pencils is not abrasive enough to scratch the glass and create a lasting mark. Additionally, the pencil lead is not easily visible on the transparent surface of glass.
