I started watching this channel when I was in high school, and I still came back as a current physics major student. Thank you!

@@hulumtuesi63 I am in university and we learn this stuff at the end of the first year for the physics study, combined with a bit more calc 3 though. But I live in Europe though so its a bit different. I believe college and university are very similar, only you can't do masters and phds at college I believe, so university is a bit higher level in that sense, in the later study years and for research.

You're carrying my class thru AP Physics. Thank you so much!

You are so welcome, however, I would say that you are carrying yourself; I am just providing support!

What a masterpiece. Big respect for your efforts devoted in each video 👍🏻👍🏻

Watching this makes little sense to me as someone who hasn't taken a calc class and who is in AP Physics 1, but It's nevertheless interesting to see some more advanced maths and physics I might tackle in the future. I just wanted to say that I really appreciate all the effort you put in and the time you spend creating these videos for us. Have a good one!

I bet it was like listening to a foreign language which you have spent some time learning, however, you are not fluent in yet. You pick up bits and pieces which make sense, but much of it incoherently, but enjoyably, washes over you.

Thank you so much for this. I wish there were videos like this back when I was in high school and university. My grades would have been much better 😅. Big up from Trinidad! 🇹🇹

Remember watching you as a first year undergrad, now a 3rd year PhD student lol. It’s wild how this stuff goes from so hard as a first year to easy so fast within like a year

you're the best plus there is humour in your videos which makes one watch till the end it's the first time watching 2 of the 30 minutes videos without a break plus you look like those scientists in moves you're awesome

25:11 When was this mentioned? I though Electric potential is the potential energy over q? (referring to 6:38). Anyway, that equation looks like the equation for Electric field, which i think was used interchangeably in 26:55. Should i say electric potential of a point charge = Electric field?

My plan is to beginning working on AP2 topic videos after I complete the APC E&M review videos. Best of luck on the AP1 exam in May!

i thought w= - q delta V ? you have it as positive and that is confusing.

Hello, I am kind of confused on whether ΔV = Va - Vb or Vb - Va, for me using Va - Vb is easier cause, in the equation delta V = Vb -Va = minus the integral from A to B E dr, I multiplied both sides by minus and then I got Va - Vb = integral from A to B E dr, cause I think ‘b’ usually represents a point of lower potential than ‘a’, so thats why I think Va - Vb makes more sense because ‘a’ is a point of higher potential so its like saying ‘higher potential minus lower potential’

ΔV = V_redprobe - V_blackprobe. That's the way a voltmeter works. By convention, the black probe is the definition of zero voltage on a Voltmeter, and the Voltmeter measures the voltage at the red probe relative to the baseline voltage at the black probe. Electrical schematics often mark a ground symbol where the voltage is defined as zero, for the circuit in question. As a charge moves from point A to point B, the work done on the charge is equal to q*(Va-Vb). Voltage at origin minus voltage at destination, all multiplied by the charge, is the work done on the charge. The change in electric potential energy is exactly the opposite, because W + ΔEPE = 0 when no other sources of energy are involved. This means ΔEPE = q*(Vb-Va), which therefore means ΔV = Vb - Va. Voltage at destination minus voltage at origin. For a positive charge, work is done on the charge as it moves from high potential to low potential, so when q*(Vb-Va) is negative, the work is positive
