Physics
Simple Pendulum Calculator
Computes the period and frequency of a simple pendulum from its length and gravitational acceleration. Use it for clock design, physics experiments, and comparing pendulum behaviour on different planets.

Physics
Escape Velocity Calculator
Calculates the escape velocity from a planet, moon, or star — the minimum speed an object needs to break free of its gravity without further propulsion. It uses √(2GM/r) with the universal gravitational constant.
