Elastic VS Inelastic Collisions: Equations and Differences

Objects that stick and objects that bounce are not the same problem. This video draws the hard line between them: perfectly inelastic collisions, where they lock together and kinetic energy is quietly lost to heat, and elastic collisions, where both momentum and kinetic energy survive and two equations must hold at once. See why equal masses swap velocities, why the general elastic formulas save you from a quadratic, and why using energy conservation on an inelastic collision is a guaranteed wrong answer. Only momentum survives a stick. Never assume kinetic energy comes with it. AUX Learning - Free Physics Resources https://auxlearning.com
