Physics
Simple Pendulum Calculator
Calculate the period, frequency, and energy of a simple pendulum given its length and swing angle. Used in physics labs, clock design, and seismology to model oscillatory motion.

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.
