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.

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 friction is a useful force?
Friction is a useful force in situations where you want to stop or slow down an object, like brakes on a car or shoes on the ground providing traction. It is also important for tasks that require grip or control, such as writing with a pencil or turning a screw.
Writing with a pencil is an example of what friction?
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.
What three ways can friction be useful?
Friction allows us to walk without slipping by providing grip between our feet and the ground. It helps to slow down moving objects, such as vehicles coming to a stop on a road. Friction is essential for writing with a pencil, as it allows the graphite to leave marks on paper.

How is using a pencil an example of friction?
Using a pencil involves friction because as you write, the graphite on the pencil's tip rubs against the paper, creating resistance. This resistance generates heat and wears down the pencil tip over time.
Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
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.
Describe 3 examples where friction is useful?
Walking is an example of friction. when friction is formed you may slow down, but you may have a weak balance and fall to your height. friction can be used in many places, like themeparks and ice skating and even on the sole of your shoes.
How is low friction useful in your life?
Friction can be very useful in your life. You need low friction when you ski. If you have high friction you cannot glide easily on the snow. You can also use low friction when you ice skate. If you have high friction you cant glide across the ice. When you use your laptop your keypad has to be able to glide. Some examples of high friction are erasing with your pencil, rubbing your hands together etc.
Is friction useful with computers?
No Friction Runes Computers
What force makes a pencil eraser work?
