Physics Hub on Instagram: "In physics, collisions are classified as elastic or inelastic based on how energy behaves during impact. 🔹 In an elastic collision, both momentum and kinetic energy are conserved. 🔹 In an inelastic collision, momentum is conserved, but some kinetic energy is transformed into sound, heat, or deformation. This simple experiment shows how time, motion, and energy change during collision — making physics visual, measurable, and real Collisions are everywhere — from bounc
