When we write with chalk on the black board, its rough surface rubs off some chalk particles which stick to the blackboard. This happens due to the friction between the surface of the black board and the chalk.

Why is it not possible to write with a chalk on a blackboard if there is no friction?

If friction was absent, the chalk deposits would not stick to the board and no mark would be left behind. This would have made it impossible to write with the chalk on the blackboard.

Why cannot we write on a smooth blackboard with chalk?

It is difficult to write with chalk on any smooth board because when the board is smooth, the friction between the chalk and the board is not sufficient. For chalk to leave marks on the board, the board must be rough so that the chalk marks are left on the board due to friction.

Why is it difficult to write on a class sheet?

this happens because chalk cannot write on a smooth surface, as glass is smoother and has lesser irregularities causing it to house less friction, the chalk will slip off when you write on a glass sheet. Q. Without friction, we will not be able to write on a blackboard with chalk.

Why it is difficult to write on a very smooth surface?

A force of friction acts at the point contact of the pen and the paper against the motion of the pen. For a very smooth paper frictional force is low and the pen slips on the paper surface. For a very rough paper frictional force is quite high and this makes it difficult to move the pen over the paper.

Why it is difficult to write on a glass surface?

It is difficult to write on the glass with a pencil because the friction on the glass is very less which creates difficulty in writing. On the other hand, since the paper has more friction it is much easier to write on paper as compared to glass.

What is the biggest disadvantage of chalkboard?
