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.

Physics
Kinetic and Potential Energy Calculator
Compute total mechanical energy E = ½mv² + mgh from an object's mass, velocity, and height — combining kinetic energy from motion and gravitational potential energy from elevation. Useful for conservation-of-energy problems in physics, engineering, and any system where energy converts between motion and position.
