May we go over the which potentials are what in equations, like force potential, KE potential… 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 doesn’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
44:57

greater than 20?
Hannah Quintero

oh 0
