Physics playground

Physics Playground – Spring & Orbit Lab

Two interactive physics simulations in one!

🔧 Spring Cannon – Compress, aim, and fire! Adjust spring stiffness, mass, gravity, and launch angle. Watch your projectile arc toward colorful targets and rack up points. Real-time energy calculations show ½kx² → ½mv² in action.

🌌 Gravity Orbits – Launch a satellite around a massive star! Tweak gravitational strength, starting distance, initial speed, and launch angle to achieve perfect orbits, collect ring points, and count how many times you circle the star.

Features:

· Drag-to-compress spring mechanic with trajectory prediction

· Realistic physics simulation (Hooke's Law + projectile motion / Newtonian gravity)

· Particle effects on collisions

· Keyboard controls (Space to fire, arrow keys for fine-tuning)

· Touch support for mobile

Play, experiment, and learn physics the fun way!
