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
Gravitational Potential Energy Calculator
Calculate gravitational potential energy GPE = mgh stored in an object at a given height above a reference level. Useful for energy-conservation problems, hydroelectric and roller-coaster design, and any analysis where elevation translates into stored energy.
