General Physics

The table below list some concepts introduced in introductory physics text books, and the equations associated with these concepts.

Fluid Mechanics:

  
Bernoulli's equation:   
 P + rgh + ½rv2 = constant.

Kinetic Theory:

  
Ideal gas law:
 PV = nRT = NkBT
Kinetic theory:
 PV = (2/3)N(m<v2>/2)
Avg. kinetic energy:
 <KE> = (3/2)kBT

Temperature and Heat:

  
Linear expansion:
 Dl = alDT.
Volume expansion:
 DV = bVDT
Thermal conductivity:   
Specific heat capacity:  
 c = DQ/(mDT)
Wien's law:
 lmax= 3´106/T.

Thermodynamics

  
First law of thermodynamics:  
 DU = DQ + DW
Carnot cycle:
 Q1/T1 = Q2/T2
Efficiency of a heat engine:
 e = W/Qhigh = (Qhigh - Qlow)/Qhigh
COP of refrigerator:
 COP = Qlow/(-W) = Qlow/(Qhigh - Qlow)
COP of heat pump:
 COP = Qhigh/(-W) = Qhigh/(Qhigh - Qlow)
Change in entropy:
 ,  dS = dQ/T
