Physics Calculators (Page 33)
Velocity, mechanics, energy, electricity and physics tools.
Acceleration Calculator
Compute acceleration a = Δv/Δt.
Gravity Calculator
Compute surface gravity g = GM/R² for a planet/body.
Work Calculator
Find mechanical work W = F·s·cosθ. Enter force, displacement and angle for work, or work, force and angle for displacement.
Electric Power Calculator
Enter voltage, current and resistance to compute electric power P = V·I = I²·R = V²/R.
Mass-Energy Calculator
Enter mass and the speed of light to compute energy via E = m·c² (rest energy).
Ohm's Law Calculator
Enter any two of voltage, current and resistance to compute the third via V = I·R.
Lens Calculator
Solve thin-lens quantities (f, u, v) for a chosen unknown.
Resistor Combination Calculator
Combine 1–3 resistors in series or parallel. Series: R=R1+R2+... Parallel: 1/R=1/R1+1/R2+.... 100Ω+200Ω series=300Ω, parallel≈66.7Ω.
LED Calculator
Compute LED current/resistor from supply, forward voltage and resistance.
Capacitor Calculator
Solve capacitor quantities (series/parallel combination, charge, time constant).
Sound Pressure Level Calculator
Enter sound pressure p in Pa to compute the sound pressure level L=20·log₁₀(p/2e-5) in dB. p=0.632 Pa → L≈90 dB. Reference p₀=20 µPa. Complements decibel and frequency tools.
Wind Chill Calculator
Enter air temperature and wind speed to find the feels-like wind chill temperature.
