Hey guys!
Have you ever wondered why dust 'appears' on your coffee tables or TV screens after you clean it with a cloth? Well, it's actually really interesting!
You see, there are three sub-atomic particles: Electrons, Protons and Neutrons.
Protons = positive charge
Electrons = negative charge
Neutrons = neutral charge
There are also 3 ways of 'charging' an object to give it a charge: Conduction, Induction and Friction.
Friction is the act of rubbing 2 objects together. When you rub the 2 objects together, a charge is transferred from the object you are using to rub and the object being rubbed. REMEMBER: ONLY ELECTRONS MOVE! So that means electrons are being transferred from the cloth to the screen you are cleaning.
Here is another important fact: OPPOSITE CHARGES ATTRACT, and LIKE CHARGES REPEL. That means the positive charges and negative charges come closer together, while 2 negative charges would go away from each other. So since the dust is negative and the screen now is negative, the dust gets attracted to the screen!
Wasn't that cool? I'll get more in depth with the words used in this article next post. Until then, stay green!
