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.

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.
