Physics Calculators (Page 13)
Velocity, mechanics, energy, electricity and physics tools.
Orbital Period Calculator
Enter the semi-major axis and the standard gravitational parameter to compute the orbital period via Kepler's third law T = 2π√(a³/μ).
Pressure Calculator
Enter force and area to compute pressure p = F/A.
Mechanical Power Calculator
Enter work and time, or force and velocity, to compute mechanical power.
Joule Heating Calculator
Compute Joule heating P = I²R and energy E = I²Rt.
RC Time Constant Calculator
Enter R, C, supply voltage Vs and time t to get τ=RC and the capacitor voltage Vc during charging and discharging. R=10 kΩ, C=100 µF → τ=1 s; at t=1 s a 12 V supply reaches ≈7.58 V (≈63.2%).
de Broglie Wavelength Calculator
Compute λ = h/p = h/(mv) for a particle.
Spring Natural Frequency Calculator
Enter spring constant k and mass m to compute the natural frequency f=(1/2π)√(k/m), period T=2π√(m/k) and angular frequency ω=√(k/m). k=100, m=1 → f≈1.592 Hz, T≈0.628 s.
RMS Molecular Speed Calculator
Enter absolute temperature and molar mass to compute the Maxwell-Boltzmann speeds: v_rms=√(3RT/M), v_mean=√(8RT/πM), v_p=√(2RT/M). N₂ at 273 K → vrms≈493 m/s, He ≈1300 m/s.
Magnetic Flux Calculator
Enter flux density, area and angle to compute the magnetic flux Φ = B·A·cosθ in webers (and maxwells).
Poiseuille Viscous Flow Calculator
Enter tube radius, length, pressure drop and viscosity to compute the viscous flow rate Q = π·r⁴·Δp/(8·η·L) of a Newtonian fluid.
Compton Shift Calculator
Compute scattered X-ray wavelength/energy after Compton scattering.
Wien's Displacement Law Calculator
Enter absolute temperature T to get the blackbody peak wavelength λ_max=b/T (b=2.89777e-3 m·K) and peak frequency. T=5778 K (Sun) → λ_max=502 nm (green, visible); T=300 K → 9.66 µm (IR).
