Two interactive panels. Panel 1 (Gravitational PE): A ball that can be moved to different heights (0-10m slider). Shows GPE = mgh updating in real-time. Mass slider (1-10 kg). Students see that higher = more PE, heavier = more PE. When they 'drop' the ball, PE converts to KE (bar chart shows PE decr
