Density is per unit volume 
Density = mass / volume 

velocity = displacement / time 

Force = rate of change of momentum 

Momentum = mass . velocity 

Power is rate of work done 
Power = work / time
Unit of power is watt 

Potential energy (P) 
PE = m.g.h 
m = mass 
g = acceleration due to gravity (9.81m/s2) 
h = height 

Kinetic energy (P) 
P = (1/2).m.v2 
m = mass 
v = velocity 

Ohm's law 
V = I . R 
V = voltage applied 
R = Resistance 
I = current 

Electric power (P) = (voltage applied) x (current) 
P = V . I = I2 . R 
V = voltage applied 
R = Resistance 
I = current

OPTICS 
Index of refraction
 
n = c/v 

n - index of refraction 
c - velocity of light in a vacuum 
v - velocity of light in the given materia
