Classical mechanics is the foundation of all physical science. Formulated by Newton in 1687, its three laws describe how forces produce motion — from the arc of a thrown ball to the wobble of a gyroscope. Despite being over 300 years old, Newtonian mechanics remains the workhorse of engineering, robotics, and space exploration.
These simulations bring the equations to life. Launch projectiles through air resistance, watch a spring-mass system trace perfect sinusoidal paths, slide blocks down inclined planes with friction, smash objects together in elastic and inelastic collisions, and spin objects to discover rotational inertia. Every simulation solves the real differential equations in real time.
