Physics Calculators (Page 11)
Velocity, mechanics, energy, electricity and physics tools.
Moment of Inertia Calculator
Enter mass and radius to compute the moment of inertia of a solid disk or hoop about its central axis.
Rotational Kinetic Energy Calculator
Enter moment of inertia I and angular velocity ω to compute rotational kinetic energy E=½Iω². I=2 kg·m², ω=3 rad/s → E=9 J; double ω → 4× energy.
Linear Expansion Calculator
Enter the expansion coefficient, original length and temperature change to compute the change in length ΔL = α·L₀·ΔT.
Beat Frequency Calculator
Compute the beat frequency |f₁ − f₂| of two close tones.
Elastic Potential Energy Calculator
Compute spring potential energy U = ½kx².
Transformer Turns Calculator
Enter primary voltage, primary turns and secondary turns to compute secondary voltage Vs=Vp·(Ns/Np) and turns ratio Ns/Np. Vp=220 V, Np=1100, Ns=100 → Vs=20 V (step-down).
Parallel Resistance Calculator
Enter two resistances to compute their equivalent parallel resistance R = (R1·R2)/(R1 + R2).
Series Resistance Calculator
Enter three resistors R₁, R₂, R₃ and instantly get the series equivalent R = R₁ + R₂ + R₃. R₁=6 Ω, R₂=3 Ω, R₃=1 Ω → R=10 Ω.
Electric Potential Energy Calculator
Enter two charges, the distance between them and permittivity to compute their electric potential energy U = k·q1·q2/r.
LC Resonant Frequency Calculator
Enter inductance L and capacitance C to instantly compute the LC circuit resonant frequency f = 1/(2π√(LC)). L=1 mH, C=1 µF → f≈5033 Hz.
Projectile Range Calculator
Enter initial speed and launch angle to compute the horizontal range R = v₀²·sin(2θ)/g of a projectile.
Projectile Maximum Height Calculator
Enter initial speed and launch angle to compute the maximum height H = (v₀²·sin²θ)/(2·g) of a projectile.
