Done with physics!
speed = distance/time
avg spd = total distance/total time
velocity = displacement/time
Acceleration=(v-u)/time
deceleration=RETARDATION(lol)
Force = mass x acceleration
Weight=mass x gravity
Moment of a force = force x perpendicular distance.
Density = mass/vol
Pressure = force/area
Pressure due to liquid column = height of column x density of liquid x gravity.
Kinetic energy = (1/2) x mass x velocity(sq)
Potential energy = mass x gravity x height
Work = force and distance
Power = work done/ time taken = energy change/ time taken
titer = (l(titer)-l(0))/(l(100)-l(0)) X 100 degrees
temp in kelvin = temp in degrees celsius + 273
e.m.f = k X titer where k is a constant.
thermal energy = heat capacity X change in temp (heat capacity)
thermal energy = heat capacity X mass X change in temp (specific heat capacity)
Thermal energy = mass x specific latent heat
refractive index = sin i/sin r
refractive index = speed of light in vacuum or air/ speed of light in medium
sin c = 1/refractive index
all fomulas. I think I'll forget them tmr anyway...
You sound so .... as if I know!
wtf. And you say .... I never even take lor.
Then I only ... ma. !!!!! Give you back la ==!
Give you 2 times back LA! you think I so
!@*# orh. wo hen low. after one msg only.
I replied ok and then no reply le. stupid.
shouldn't msg you in the first place la.
make me so low only. wth.
I don't want your ........ I want ..... D:
lol. type so much = type nothing anyway.
I'll earn back for you. don't worry.
I'm not the type of person you think I am.
!@&#@. Ha. I very guai le. never use those
"nice" words le. =X still studying A-maths now.
I don't understand alpha beta. crap.
what this sq tt sq. roar. and i like at chap 3 only?
no sleep for me tonight! byee.
