This virtual Rube-Goldberg machine contains and demonstrates seven principles of physics over a time span of at least 14 seconds: elastic collision, inelastic collision, torque, conservation of energy, conservation of momentum, and projectile motion in two dimensions. In the simulation, air resistance is negligible, and gravity is constant, which means circular motion is constant as well. The purpose of this machine is to topple an egg in the final step. My machine demonstrated the seven principles of physics and was successful in its purpose as it functioned smoothly. In the end, the entire process has exceeded 14 seconds.
