This project demonstrates the fundamental principles of energy conversion through an interactive roller coaster simulator. The simulator visualizes how kinetic energy and potential energy transform into each other as the roller coaster moves along its track. When the coaster is at the highest point, it has maximum potential energy and minimum kinetic energy. As it descends, potential energy converts to kinetic energy, increasing its speed. The project includes two implementations: a Minecraft roller coaster simulator showing energy changes at different heights, and a Python simulation that models the physics of kinetic and potential energy transformation throughout the ride.
