Smartphones in theme parks reconstruct 3D ride trajectories to teach Newtonian mechanics

Using Theme park rides and smartphones for demonstrating Newtonian mechanics

Researchers used smartphones to record acceleration and orientation on a roller coaster and a pendulum ship, then applied inertial odometry to reconstruct full 3D trajectories. The roller coaster path matched satellite imagery within 5 meters, revealing launch acceleration, loop dynamics, and energy exchange. The pendulum ship showed periodic motion and energy input during driving. This approach enables detailed mechanical analysis, including kinetic and gravitational energy, offering an accessible platform for teaching mechanics through real-world experiences.
