Electric Charge: Crash Course Physics #25

42 Comments

1. I wish Hank redid physics.

2. I have a question that I hope someone can answer
   At 2:43
   That cloth is negatively charged since electrons move from the rod to the cloth
   But why didn't electrons move from the cloth to the rod?

3. Is that a lego millenium falcon in the top corner?

4. At 3:25, why does the contact between the positive and the neutral rod transfers electrons? Aren't they glass rods, and thus, insulators?
   And if there is a reason for electrons to flow that way, why don't they travel through me and get "grounded", thus, neutralizing the charges?

5. this is a really great video but i cant find a simple answer to "what is charge?"

6. 3:58 huh? Audio?

7. 7:10
   "The constant is 9 * 10^9 Coulombs"
   But it's 9 * 10^9 Nm^2/C^2… Does Nm^2 = C^3? I don't think so…

8. The animations are adorable. I thought it was cute how the fur slapped the amber lol

9. God,! She speaks fast.

10. 4:53 look who we have here lmao

11. I must have watched it like 5 times now and every time I'm at the end I am certain I don't know what it was about…I think it is the lack of really tangible examples and the shear pace and scope of science covered during that super fast pace that limits comprehension and retention of the material. Pointless

12. Am I the only one who need to study this in school

13. equilibrium is relative, entropy is ultimate

14. I'm in 8th grade and our teacher act's like we're preschoolers

15. OMG 😱 too fast!!!

16. That tape thing just blew my freaking mind 😳

17. You fail at explaining

18. you are so fast when you talking please slowdown

19. Mam i am unable to understand because of your so high class accent. Sorry to say mam but i am very eager to understand this .

20. Hi! Loved the animations. Can I show them to my students?

21. Cthulu 2020

22. Hi people could u help me with some names of books that helps me understand this better especially the columbs law

23. Isolation brought me here :/

24. what is this

25. You look so young but so smart jeez I wish you were teacher but u talk tooo fast yet still understandable lol

26. Can you not move along so quickly? It is impossible to gather all of the information and process it when you explain it all in such a hurry

27. I was easily able to see her eyes looking at the screen behind the camera

28. Talking on fast forward makes it hard to absorb the good information. Slow down, what’s the rush?

29. 6:01 what?

30. Subhanillah

31. For "charged by contact" and polarization, I thought that if an electron was already "linked" to a proton it wouldn't be drawn to anything else.. The electrons go towards the area with more protons because the bigger positive charge breaks that attraction it had with that sole proton it was originally linked to? Great video though I would have liked to have it all explain from this point as it becomes even more fascinating.

32. Huh?

33. This whole physics series is really helpful

34. i fell asleep 7 times

35. Objects do not gain positive charges. they either gain or lose electrons for this level

36. Online School?

37. what are the odds of getting a mini crash course series on electricity alone? There is so much content, from basic theory, AC vs DC, current, motors / generators, different kinds of load on a circuit, different electrical components ect.

38. 2:33

    woah there

39. A good physic teacher can make you fall in love with physics and she did it like a pro.

40. Who here for quarantine learning

41. She be smrt

42. She can REPLACE MY school
