🎢 Can a roller coaster really do a loop without falling? Yes, and physics tells you exactly why. Drag the starting height and watch the cart climb, dive, and take the loop while the energy bar changes: 🟠 potential energy → 🟢 kinetic energy → 🔴 heat lost to friction Lower the start height and the cart won't make it over the top. Find the minimum height for yourself, then check it against the formula 🤓 ✔ Live speed, height, acceleration, and G-force ✔ The numbers match the textbook formulas ✔ Free, in your browser, works on phones 👉 Try it: https://physlabo.com/en/physics/mechanics/energy/energy-conservation-roller-coaster/?utm_source=telegram&utm_medium=social&utm_campaign=roller_coaster More interactive physics simulators: mechanics, electricity, optics, quantum physics 🔬 🌐 physlabo.com/en/ #physics #rollercoaster #simulation #STEM #education
