stfu you son of a bitch....you are one really ridiculous piece of shit.....you need your damn head kicked in and by God I am the one to do it.....you are worthless all you do is your damn retarded little one line stupid shit over and over..
you're snf faggot and your mom is a fat whore with three teeth and aids..

while that is interesting
static equilibrium requires both rotational and translation equilibrium. There is no net force!
Fnet = 0
Then sumFx = 0
sumFy = o
And the torques equal 0. So up = down, left = right, and clockwise = counterclockwise.

The important thing to remember is that for torques, you include distance, and for Fx and Fy you do not. You gotta use the trig to get the perpendicular part of the force.

It's important to know that where you put the pivot, the forces at that point do not exist.

@previous (Triptych !IupsXZPnnU)
huh there were fewer notes on this than i thought

okay static electricity!
neutral material is pulled by charges
Q = ne -> quantity of charge (in Coulombs: C) = number of fundamental charges * fundamental charge
fundamental charge = +- 1.6*10^-18 C

Coulomb's law:
Fe = k (Q1Q2)/r^2 where k is coulomb;s law constant, 9e9

·Triptych !IupsXZPnnU — 12.7 years ago, 1 minute later, 1 day after the original post[T] [B] #350,756

static electricity:
objects not in motion
point charges
E -> electric field - vector
E = (kQ)/r = Fe/Q
arrows for a field diagram point where a positive charge will go

·Triptych !IupsXZPnnU — 12.7 years ago, 1 minute later, 1 day after the original post[T] [B] #350,757

fuck i hate this i just want to go back to bed but that will be shit too
fields are vectors
Et = E1 + E2
i'm only here until thursday that is a good thing because i just feel very sick and dead-winter
parallel plates
the field gets concentrated!
Ep = QEd, some derivation of that with a relation to gravity where Ep = mgh

·Triptych !IupsXZPnnU — 12.7 years ago, 58 seconds later, 1 day after the original post[T] [B] #350,758

i'd be sorry for hijacking your thread if it weren't kind of shit
electron gun
no field outside the charges - it;s all concentrated in
a diagram i should remember

·Triptych !IupsXZPnnU — 12.7 years ago, 1 minute later, 1 day after the original post[T] [B] #350,759

potential energy:
uniform field:
Ep = QEd
Ep = mgh

point charges:
Ep = kQ1Q1/r
Ep = -Gm1m2/r

parallels with gravity yeah

whole energy shite

·Triptych !IupsXZPnnU — 12.7 years ago, 47 seconds later, 1 day after the original post[T] [B] #350,760

voltage important
Ep is electrical potential energy
Voltage is just electrical potential - similar to pressure, the energy per C

V = Ep/Q
units are J/C

·Triptych !IupsXZPnnU — 12.7 years ago, 2 minutes later, 1 day after the original post[T] [B] #350,762

V = Ed
V = kQ/r
Voltage is a scalar
Vt = VQ1 + VQ2...

handy chart of formulae
E = Fe/Q E = kQ/r^2
Fe = QE Fe = (kQ1Q2)/r^2
Ep = QEd Ep = (kQ1Q2)/r
V = Ep/Q V = kQ/r V = Ed

i am going to kill myself

something important:
for a cathode ray tube with parallel plates to find the deflection of an electron:
first find velocity
second find time
third find electric field
fourth fine Fe on electron
last fine distance

capacitors
they hold charge
the bigger the surface area the greater the capacity
C = Eo A/d
Eo = 8.85e-12
C = Q/V
1 Farad = 1 Coulomb/1 Volt

·Triptych !IupsXZPnnU — 12.7 years ago, 4 minutes later, 1 day after the original post[T] [B] #350,768

Ep = 1/2CV^2
QV = deltaEp
Capacitors in parallel: CTp = C1 + C2...

Capacitors in series:
1/CTs = 1/C1 + 1/C2 +...
actually is less

·Triptych !IupsXZPnnU — 12.7 years ago, 31 seconds later, 1 day after the original post[T] [B] #350,769

dielectrics

C = kEo A/d
E goes down = V/d

·Triptych !IupsXZPnnU — 12.7 years ago, 1 minute later, 1 day after the original post[T] [B] #350,772

Current electricity (I)
I = Q/t = C/S = Ampere = Amp = A

conventional current
I travels from + to -

Electron flow:
travels from - to +
