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 + ρgh + ½ρv^{2 }= constant. 
Kinetic Theory: 

Ideal gas law:  PV = nRT = Nk_{B}T 
Kinetic theory:  PV = (2/3)N(m<v^{2}>/2) 
Avg. kinetic energy:  <KE> = (3/2)k_{B}T 
Temperature and Heat: 

Linear expansion:  Δl = αlΔT. 
Volume expansion:  ΔV = βVΔT 
Thermal conductivity:  ΔQ/Δt = kA ΔT/Δx 
Specific heat capacity:  c = ΔQ/(mΔT) 
Wien's law:  λ_{max}(nm) = 3*10^{6}/T(K). 
StefanBoltzmann law:  Radiated power = σ * T^{4} * Area. 
Thermodynamics 

First law of thermodynamics:  ΔU = ΔQ  ΔW 
Carnot cycle:  Q_{1}/T_{1 }= Q_{2}/T_{2} 
Efficiency of a heat engine:  e = W/Q_{high }= (Q_{high } Q_{low})/Q_{high} 
COP of refrigerator:  COP = Q_{low}/(W) = Q_{low}/(Q_{high } Q_{low}) 
COP of heat pump:  COP = Q_{high}/(W) = Q_{high}/(Q_{high } Q_{low}) 
Change in entropy:  ΔS = ∫_{i}^{f} dS = ∫_{i}^{f} dQ_{r}/T, dS = dQ/T
