Physics Calculators (Page 8)
Velocity, mechanics, energy, electricity and physics tools.
Angular Velocity Calculator
Compute angular velocity ω = θ/t and the related linear velocity.
Work Done Calculator
Enter the force, displacement and angle to compute the work W=F·d·cosθ, quantifying the energy transferred by a force. Pushing 50 N over 3 m (same direction) → W=150 J.
Efficiency Calculator
Compute efficiency η = useful output / total input.
Electric Field Calculator
Compute electric field E = kq/r² from a point charge.
Photon Energy Calculator
Enter frequency or wavelength to compute photon energy E = h·f = h·c/λ (in joules and eV).
Latent Heat Calculator
Compute heat Q = m·L for a phase change.
Ideal Gas Law Calculator
Enter any three of moles, temperature, volume and pressure to compute the fourth via PV = nRT.
Capacitor Energy Calculator
Compute energy stored in a capacitor E = ½CV² = Q²/(2C).
de Broglie Wavelength Calculator
Compute λ = h/(mv) for a particle (alt units).
Decibel Calculator
Convert between ratio and decibels: dB = 10·log10(P₂/P₁) or 20·log10(V₂/V₁).
Calorimetry Calculator
Compute heat to change temperature Q = m c ΔT.
Graham's Law Calculator
Compute effusion rate ratio r₁/r₂ = √(M₂/M₁) of two gases.
