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
Force Calculator (Newton's Second Law)
Calculate the net force on an object from its mass and acceleration using Newton’s Second Law, F = m·a. The cornerstone of classical mechanics, used everywhere from sizing motors to estimating brake forces to predicting how hard a ball will hit the ground.
