Density D = M/V

Density = Mass/Volume
(Kg/m^3) 

Young's strech modulus Y = FL/A*L
* triangle 
Young's stretch modulus = Force(Original Length)/Area(change in length)


Idea efficiency of a heat Engine (T^hot  T^cold)/T^hot

Temperature of resivor hot  " cold/ " hot


Wave speed V = A*f

wavespeed = wavelength(frequency)


Frequency and period T = 1/F

Period = 1/Frequency
(Hz, Hertz) 

Period of a pendulum T = 2pi (square root) L/G

Period = 2pi (square root) Length/Accelaration due to gravity (9.8m/s)


Snell's law n1sin(theta)1 = n2sin(theta)2

number #1 sin (theta) #1 = number #2 sin (theta) #2


Speed of light c = A*f

speed of light = wavelength(frequency)


Index of refraction n = c/v

Index of refraction = speed of light (3 x 10^8m/s)/speed of light in material


Coulomb's law F = kq1q2/d^2

force between 2 charged particles in newtons (N) = (9 x 10^9N x m^2/c^2)(#1 charge on the particle)(#2 charge on the particle)/distance between them in meters(M)^2


Electric power P = IV

Power(P) = Current(A)(voltage)(V)


Ohm's law I = V/R

Current(A) = Voltage(V)/Resistance(U*)
