@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.
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.
That is a fundamental constant. In other words, that is something that is fundamentally true in the universe. We find this by observing the physical world. Every electron has a charge of -1.6x10^19 Coulombs.
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.
I'm so lucky I stumbled upon your channel. Nothing, (and I mean nothing) was clicking until I watched your videos. You have a gift, Derek.
you are better than any math/physics teacher i've ever had. i appreciate this soooo much.

So good, I only now understood the concept of elementary charge. Thank you so much.
geeze. you make this ALOT simpler than my professor. all my professor does is show slides of the equation and solution. kudos to you man thanks
Thanks! I do have an index at the videos at the Lucid Education website. Enjoy!
thank you very much for these clear explanations. every school should have videos like this:). learning would be so much easier, and fun!
This is really going to be beneficial for my quiz later tonight! Thanks

Thanks. Very clearly explained!
Why are electrons referred to as elementary particles if they themselves are made up of quarks?
from where did you get 1.6*10^-19

@JesusWasADerelict Hadrons are made from quarks. Electrons are Leptons, not Hadrons -- they haven't been shown to be composites of anything else.
This equation is correct (and so is the number) where epsilon zero is the permittivity of vacuum
how did he come up with the equation f=kq1q2
@JesusWasADerelict Because we can never break an electron apart into its constituent quarks.
better than my teacher, thanks haha
@JesusWasADerelict electrons are not made of quarks. Protons and neutrons are.
So quarks are not considered as elementary charged particles ??
I believe that is correct, and I think the reason for that is that you cannot isolate an individual quark.
Good teacher I understand now
thank u！
is the Force billions of Newtons, or billionths of Newtons? I mean, is it 3.28 followed by 9 ceros, or 0. then 9 ceros and then 328?
at 5.24 he says we put that on calculator how can we put this value on calculator
its realy nice sir
Is this universitary physics level? because if it is, i'm gonna start watching along my clases
This is "high school" level in the US, grades 9 through 12, preparation for college but not college level.
Derek Owens thanks!
@derekowens Alright gotcha, cheers
why is the formula based on squared why cant it just me metres ? Anyone answer that for me whats the reason for taking an area ?
Better than khan academy! I suggest you organize your videos in a more user friendly way and you'll have tons of hits in no time
i hope that i meet u cause u r very smart...
I think I love you
i didnt get the equation

wtf why didnt my teacher tell me this shit lol
@kakkannon wow man just get out lol
Then dont watch the video and stop crying
