Physics Calculators (Page 20)
Velocity, mechanics, energy, electricity and physics tools.
Drude Model Calculator
Enter carrier density and relaxation time to compute metal conductivity σ=ne²τ/m and mobility μ=eτ/m. Copper n=8.5e28, τ=2.5e-14 → σ≈5.99e7 S/m.
Quantum Hall Resistance Calculator
Enter the Landau level filling factor to compute the quantized Hall resistance R_H = R_K/ν, where R_K = h/e².
Biot–Savart Law Calculator
Compute the magnetic field from currents (straight wire and loop).
Carnot Cycle Calculator
Compute Carnot efficiency and heat-pump/refrigerator COP.
Fresnel Equations Calculator
Compute reflectance and transmittance at a flat interface (normal incidence).
Compton Scattering Calculator
Compute the Compton wavelength shift Δλ = λ_c(1−cosθ).
Poynting Vector Calculator
Enter electric field amplitude to compute the average/peak intensity, magnetic field amplitude and total energy density of an EM wave.
Adiabatic Process Calculator
Compute volume/pressure relation and work for an adiabatic gas process.
Entropy Change Calculator
Enter moles, heat capacity, temperatures and volume ratio to compute the entropy change of an ideal gas ΔS = n·Cv·ln(T2/T1) + n·R·ln(V2/V1).
Venturi Flow Rate Calculator
Enter upstream area, throat area, pressure difference and density to compute Venturi-tube flow rate Q=A₂√(2ΔP/(ρ(1−(A₂/A₁)²))). A₁=0.01, A₂=0.001, ΔP=5000 Pa, ρ=1000 → Q≈0.00318 m³/s, v₂≈3.18 m/s.
Bulk Modulus Calculator
Compute bulk modulus K = −V·Δp/ΔV and compressibility.
Shear Modulus Calculator
Enter shear force F, area A, shear distance L and lateral displacement Δx to compute shear modulus G=F·L/(A·Δx). F=1000 N, A=1e-4 m², L=1 m, Δx=1.26e-4 m → G≈79.4 GPa (close to steel).
