- This lecture is about charge at the microscopic scale. It will tell you about the charge and mass of subatomic particles, and the numerical values and units of those values.

you are awesome explaining these physical concepts in beauty , i really hope you start making videos for optics and microwaves courses .
Just want to say I got an A on my first physics II exam using these videos, my webassign homework, and my book physics for scientists and engineers by serway. Recommend these videos
Congrats!!
I highly recommend Prof Hafner's Physics courses wherever you can find them. E.g. Coursera.org has the Freshman mechanics series.
Unfortunately, edX course is unavailable:
Electricity and Magnetism, Part 1
RiceX - PHYS102.1x
Access expired on Apr 7, 2020 for Electricity and Magnetism, Part 1
Brilliant explanation & example. Tq
Can we say this much Coulomb of charge will create this much Newton of force?
Yes, but you would need two charges (and two quantities of Coulombs) to have a force.
@@Prof-Hafnerforce always acts in the same direction and in the same magnitude to all the bodies within it's field.
Charge in some case repels and in some case attracts and this happens only with another charge, not with all the bodies.
Is this the reason we have a separate name 'charge' instead of calling it just 'force', to distinguish the properties?
"charge is property of matter that creates force". GREAT.
Then, why don't we just call it force only?
Because you need the scalar quantity to make the vector force.
@@Prof-Hafner any more recommendations to understand charge more fundamentally?
