Physics 12.2.2a - Elementary Charge

[LLiimmzz]

wtf why didnt my teacher tell me this shit lol

[ChickCalculus]

Are there really students learning about electromagnetics that haven't taken alegebra 2? Ahh, I'm just learning this stuff and I'm my second year of AP Calc BC.

[MsTightman]

can u please explain what is mean by ''k'' in equation i know that is constant but what does it really means.

[derekowens]

@MsTightman k is one of the constants of the universe. It is basically a number that tells us how strong the electrostatic force is. Just like G is a constant for the gravitational equation, k is a constant for the electrical forces.

[MsTightman]

@derekowens u rock i am extremely thankful!

[MsTightman]

welldone!sir



[backyardbeachbum]

you are better than any math/physics teacher i've ever had. i appreciate this soooo much.

[JesusWasADerelict]

Why are electrons referred to as elementary particles if they themselves are made up of quarks?

[derekowens]

@JesusWasADerelict Because we can never break an electron apart into its constituent quarks.

[JesusWasADerelict]

@derekowens Alright gotcha, cheers

[riahmatic]

@JesusWasADerelict Hadrons are made from quarks. Electrons are Leptons, not Hadrons -- they haven't been shown to be composites of anything else.

[DeltaNordicAdvance]

@JesusWasADerelict electrons are not made of quarks. Protons and neutrons are.

u make physics easy!! and i wish u were my physics teacher !

[kingofstride]

Thanks. Very clearly explained!

[Paramedic12100]

Thank you for your great videos!

[trucorky]

thank you very much for these clear explanations. every school should have videos like this:). learning would be so much easier, and fun!

[jeoyanda]

I usually see that e with a (-) negative sign in the superscript to represent electron. That negative sign shows that there is a negative charge in the electron.

[2Bitter2bSweet]

you are AMAZING!!!! i loveee you for helpin me understand physics!! thank you!

[ffddssaavvccxxzz]

i hope that i meet u cause u r very smart...

[hyphysimon]

this is great dude. it helps

[kakkannon]

you spend 3 minutes explaining that charge only increases or decreases in multiples of e....

i get it.

[ballsoffury4]

Then dont watch the video and stop crying

[MFLOVEify]

@kakkannon wow man just get out lol

[bean92ful]

This is really going to be beneficial for my quiz later tonight! Thanks
