Physics Calculators (Page 31)
Velocity, mechanics, energy, electricity and physics tools.
Resistance Calculator
Enter voltage and current, or resistivity, length and cross-section, to find resistance and power. V=10V, I=2A → R=5Ω, P=20W.
RMS Value Calculator
Enter the peak value to compute the RMS (sine: Vrms=Vmax/√2=Vpp/(2√2)), peak-to-peak and form factor. HK mains 311 V peak → 220 V RMS; sine form factor 1.1107.
SHM Displacement Calculator
Enter amplitude, angular frequency, time and phase to compute SHM displacement x=A·cos(ωt+φ), plus velocity v=−Aω·sin(ωt+φ), acceleration a=−ω²x and period T=2π/ω. A=0.1, ω=2, t=1, φ=0 → x≈−0.0414 m.
Wave Properties Calculator
Enter wave speed and frequency to compute wavelength and period. Sound v=343, f=440 → λ≈0.78 m.
Lens Formula Calculator
Compute 1/f = 1/u + 1/v and magnification for a thin lens.
Hall Voltage Calculator
Compute Hall voltage V_H = I·B/(n·q·t) directly.
Thermal Expansion Calculator
Enter original length, expansion coefficient and temperature change to get linear, area and volume expansion. Steel rail L₀=10 m, ΔT=50°C → ΔL=6 mm.
Isothermal Process Calculator
Enter initial pressure/volume and final volume to compute the work, heat and internal-energy change of an ideal-gas isothermal process.
Lenz's Law Calculator
Compute induced EMF and current ε = −N·ΔΦ/Δt.
Parallel Plate Capacitor Calculator
Enter area, separation and relative permittivity to compute capacitance, charge, energy, field and surface charge density.
Motional EMF Calculator
Enter magnetic field, conductor length, velocity and resistance to compute motional EMF and induced current.
Coefficient of Restitution Calculator
Compute the coefficient of restitution e and kinetic-energy loss in a collision.
