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
Momentum Calculator
Quickly find the linear momentum of any moving object by entering its mass and velocity. Use it in physics problems, collision analysis, or when applying Newton's second law.
