Elastic Vs Inelastic Collisions And Restitution
A split-screen comparison shows two steel spheres colliding elastically, bouncing apart with no energy loss, while two clay spheres on the other side collide inelastically, deforming and radiating sound as kinetic energy is lost. A central equation links the relative separation and approach velocities through the coefficient of restitution e, showing how e=1 means perfectly elastic and e<1 means energy dissipates. Useful for physics students studying momentum, energy conservation, and collision mechanics.

The prompt that made it
Scene 2: Elastic vs. Inelastic Collisions & Coefficient of Restitution ($e$)Visual Prompt: Side-by-side animated comparison on a split screen:Left (Elastic, $e=1$): Two steel spheres bounce off each other perfectly with no energy loss; mechanical energy is conserved. Right (Inelastic, $0 \le e < 1$): Two clay spheres collide, deforming permanently with sound waves radiating outwards; kinetic energy decreases. Center Overlay: Equation display:$$v_B' - v_A' = -e (v_B - v_A)$$ Text / Voiceover: "The Coefficient of Restitution $e$ defines collision elasticity. When $e=1$, the collision is perfectly elastic. When $0 \le e < 1$, mechanical energy transforms into internal deformation, heat, and sound."
