Question: User: Visual Prompt for AI Video Generator:Prompt: A dynamic split-screen 3D educational graphics sequence. On top, a horizontal spring-mass system oscillates smoothly. Below, real-time bar charts dynamically update total mechanical energy $E = KE + PE = \frac{1}{2} k A^2$. At $x = +A$ and $x = -A$, Potential Energy ($PE$) fills to 100% in red while Kinetic Energy ($KE$) drops to zero. As the mass accelerates toward center $x = 0$, $PE$ converts completely into $KE$, filling the blue $KE$ bar to 100% at equilibrium. The combined bar height remains completely constant throughout the cycle.English Voiceover & Text:Voiceover: "Throughout every cycle, energy continuously transforms. At extreme displacements $+A$ and $-A$, mechanical energy is stored entirely as elastic potential energy. As the mass snaps toward the center, potential energy fully converts into kinetic energy. Despite this continuous exchange, total mechanical energy remains strictly conserved."
