Computes Lorentz factor, time dilation, length contraction, relativistic energy, and momentum for a given speed

Calculates Wien peak wavelength/frequency, Stefan-Boltzmann radiant exitance, and total radiated power for a blackbody at a given temperature

Calculates post-collision velocities, momentum, and kinetic energy loss for a head-on collision between two masses with configurable restitution.

Solves constant-acceleration kinematics: given any three of displacement (s), initial velocity (u), final velocity (v), acceleration (a), and time (t), returns the remaining two unknowns.

Solves the thin lens/mirror equation for the unknown quantity (focal length, object distance, or image distance) given the other two, and returns magnification plus image properties.

Computes the period and frequency of a simple pendulum (with exact large-angle correction) or a mass-spring system given physical parameters.

Calculates wave speed, frequency, and wavelength relationships, plus Doppler-shifted frequency for sound (moving source or observer) or light (relativistic).

Calculates the refracted angle between two optical media using Snell's law, and checks for critical angle and total internal reflection.

Calculates mechanical work (force × distance × cos θ), kinetic and potential energy, and power across multiple unit systems including joules, kWh, calories, and horsepower.

Calculates weight components, normal force, static friction limit, slip/no-slip verdict, acceleration, and slide time for a block on an inclined plane.

Calculates projectile motion parameters (range, max height, flight time, impact speed and angle) from launch speed, angle, height, and gravity, without air drag.

Calculates circular orbit speed, escape speed, and orbital period at a given altitude or radius around the Sun, planets, the Moon, or a custom mass.
