About this app

🧪 Physics Playground is a hands-on classical-mechanics lab that runs entirely offline. Watch real physics unfold ⚙️ with live velocity and force vectors and real-time energy graphs, then build your own experiments from scratch.

SEVEN LIVE EXPERIMENTS
💥 Collisions — elastic and inelastic; see momentum and energy conserved (or not).
⏱️ Pendulums — single and the chaotic double pendulum.
⚪ Newton's Cradle — momentum passing cleanly through the chain.
🎯 Ballistics — projectile motion with air drag, bouncing through a peg field; tap 👆 to set the launch point.
📐 Inclined Plane — friction vs. gravity 🌍 with force vectors drawn out.
🪐 Orbits — central gravity: circular, elliptical and escape trajectories.
🌀 Springs — mass–spring oscillators obeying Hooke's law.

📊 MEASURE EVERYTHING
⚡ Speed, momentum and energy update live as the simulation runs. A conservation badge tells you at a glance when total energy stays constant and an energy-over-time graph shows kinetic vs. potential trade-offs.

STUDIO — MAKE IT YOUR OWN
💾 Presets — tweak any experiment's parameters and save your own presets.
🔗 Systems — combine several presets to watch them run side by side.
🧱 Sandbox — a real physics playground. Place balls, heavy masses, anchors, gravity wells, springs, rigid threads and walls into one shared world, then press ▶️ Play and watch everything interact. Drag ✋ to move, undo your last step and use fullscreen with 🔍 pinch-to-zoom and pan.

🎨 DESIGNED TO BE READ AT A GLANCE
✨ Glowing bodies, drawn vectors and clean instrument-style readouts on a dark theme 🌙 Everything is rendered procedurally on your device.

🔒 PRIVACY FIRST
🚫 No accounts. 🚫 No ads. 🚫 No trackers. 🌐 No internet connection is ever used — every simulation runs entirely on your device 📷 Camera and photo access are optional and only used to set a photo backdrop or save a snapshot to your gallery.

🎓 Great for students, teachers, curious minds and anyone who loves exploring how the physical world works!
