Physics formulas for high school
Density is mass 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 material.
