May we go over the which potentials are what in equations, like force potential, KE potentialâ€¦ What exactly is the difference of theta g vs. Theta r in gravitational potential energy?

Melanie Huynh

09:19

not sure

Melanie Huynh

09:31

height?

Hannah Quintero

09:39

uphill or downhill

Melanie Huynh

11:27

when would you prefer scalar over vector

Hannah Quintero

11:43

top of the hill

Corina Badea-Mic

11:44

peak

Hannah Quintero

12:34

going uphill?

Hannah Quintero

12:45

downhill

Corina Badea-Mic

13:09

perpendicular to arrows

Hannah Quintero

16:03

going away

Melanie Huynh

16:56

what if we had a charge diagonal from that top charge?

Melanie Huynh

17:02

yeah

Melanie Huynh

17:04

like in a triangle shape

Melanie Huynh

17:32

i was confused about that since there are 3 charges and the others would affect it at an angle

Melanie Huynh

18:51

how would you know when one line is bent or going straight?

Cristina Covarrubias

21:14

To the right

Melanie Huynh

21:14

down right?

Hannah Quintero

21:15

right

Melanie Huynh

21:30

down

Linh Pham

21:31

down

Melanie Huynh

23:58

because we havea third charge?

Melanie Huynh

24:39

how would we add 3 vectors like that

Hannah Quintero

27:05

less steep slope

Sofia Adriasola

27:09

Its weak? Less dense?

Hannah Quintero

28:29

they cancel out

Sofia Adriasola

28:30

Cancels out?

Corina Badea-Mic

28:31

cancel out?

Linh Pham

28:31

cancels

Aryana Nabavi

30:36

Does the test charge itself have its own electric force?

Sofia Adriasola

30:38

qE

Hannah Quintero

30:41

q times E

Sofia Adriasola

32:42

down

Hannah Quintero

32:52

drops

Sofia Adriasola

33:49

No force?

Hannah Quintero

33:58

perpendicular to lines

Aryana Nabavi

36:19

so for the force of a source charge whose PE doesnâ€™t change, the force must keep changing direction?

Aryana Nabavi

38:01

sorry did you say that E is the same for a source charge at every point on an equipotential line?

Aryana Nabavi

39:51

Charge differece

Sofia Adriasola

39:54

V = E-IR

Hannah Quintero

41:55

k*Q/r^2

Aryana Nabavi

43:47

a negative charge?

Hannah Quintero

43:49

positive

Aryana Nabavi

43:49

Or positive

Melanie Huynh

44:57

capacitors

Sofia Adriasola
