Why momentum stays constant even when kinetic energy vanishes
In short: Understanding how objects interact requires distinguishing between what is preserved and what is lost. This video explores the fundamental physics of collisions, demonstrating why linear momentum remains constant while kinetic energy behaves differently.
The core distinction between elastic and inelastic collisions lies in the conservation of energy. While linear momentum is conserved in every collision, kinetic energy is only maintained in perfectly elastic ones.
By examining various demonstrations, Paul Andersen illustrates how objects exchange motion and energy, providing a clear framework for predicting outcomes in physical interactions.
