🎢 Roller Coaster
Objective: Design and test roller coasters. Place track segments (straight, drop, loop, hill, banked turn) to build a complete circuit. The car must maintain enough speed to complete the track without excessive g-forces.
Controls: Select a segment type and click to add. Click existing segments to select/drag. Press Test to run the car. G-force indicator shows safe (green) vs dangerous (red) zones.
Physics: Realistic roller coaster physics with conservation of energy. Speed determined by height changes. Centripetal force in loops and banked turns. G-force calculated from normal acceleration.
