We are nearly finishing posts for fundamental forces. First I would like to apologize that I forgot to mention that force carrier for Electromagnetism is photon.
So weak interaction is pretty weak but still insanely stronger than gravitation. It works with quarks and their flavors and it is responsible for decay.
Here on left is picture of all six possible flavors of quarks. (There can also be antiflavors). Most of matter in universe is made up by up and down quarks. For example neutrons and protons.
Force carrier for weak interaction is w+ boson w- boson or z0 boson.
I was talking about decay so I will show you how beta decay is made by weak interaction.
There is proton with two up quarks and one down quark. It wants to change to neutron because that particle in which this proton is is not stable.
When proton touches neutrino which is carrying w+ boson, boson will move to proton and change one up quark to down quark which makes up neutron. Neutrino will lose positive charge of boson which means it will turn to electron which makes up beta decay!
For summary I would say that weak interaction is responsible for changing of quarks flavor which is many atributes of quarks.
Well that was quite short but that is probably all.
PS. here are links to previous episodes of four fundamental forces:
today I will return to electromagnetism as second fundamental force.
It is made up two forces which we are thinking like extremely different ones.
First I will talk about electro static force.
Well, It is quite easy. When you have two objects and one wants to give electron while the other would like to take some electrons and you will make them touch each other electrons will be jumping there creating one object negatively charged and second one positively charged. (F.g. when you pull your christmas sweather on you, in dark you can probably see little lightings and feel those small shocks.) It is the same wiith battery, one side wants to have electrons so when it is charged it does not have them while second one has lot of electrons but it doesn´t need them so through some wire this difference will be slowly going to equalize by flow of electrons.
Magnetism also works with electrons and that is why these forces could be connected to electromagnetism. Magnet is made up by some special material in which atoms are turning by their pluses and minuses. So in every magnet there are millions of magnets. It does not matter if you make it smaller there will always appear new south and north pole which is made by this turning of atoms.
+ -+ –
Here on right would be south pole (+) and on left would be north pole. It it would be really light (not heavy) and it could easily turn it would be kind of compass.
At last if teacher told you that others things that are not created by Fe,Co,Ni cannot interact with this force they are wrong because you can actually find videos of levitating strawberries because of extremely strong electromagnetic field.
There is also very special attribute of electromagnetism, if you have wire without elctricity and magnet somehow rotating around you can create electricity.
That is way to create elctricity for your house. For example water flowing rotating turbine and magnets around wire is way to get energy. Or by wind rotating turbine or hot H2O flowing in reactor.
Thats about it.
Hi again, for fourth time!
I am subscribing some science channels on youtube. SciShow, VSauce, MinutePhysics or Veritasium. They are all awesome and I would like to recommend them to you. Plus I would like to thank to them because I learned a lot of stuff from them.
Anyway, few weeks ago I watched serie from SciShow. There were videos about fundamental forces. Because I would like to write about what i learned on this blog it inspired me to do something similar and try to explain what are those fundamental forces.
This post will only be about what are they together and then I want to talk about them one by one.
So there are four fundamental forces. You could also say basic forces. They have some similarities and all of them have force carriers.
First one is gravitation. It is probably the most strangest one. Gravitation is strange because it only pulls things together. Gravitation is atribute of every particle with mass. It is also crazy weak. Electromagnetic pull between two particles with different charge is 10^42 stronger than gravitation between two particles!
Next one is electromagnetism. It occurs between two objects with some charge. On the beginning of 19th century electromagnetism was created by putting together electric force and magnetic force.
Another is weak interaction. It is (for me) far more complicated i think. It affects very small stuff like quarks. It is also responsible for beta decay. Its carrier is photon.
Last one, also very complicated is strong interaction. Strong interaction is very strong. It is that strong that it can create new massive particles! Again it works on small scale and its force carrier is gluon.
Well that was short overview for fundamental forces. I will talk about them later, one by one.
Thank you for your likes and comments, as I said before, I really appreciate them!
PS. something about radioactive decay is coming!
