About this Simulation

This simulation models a rolling bottle containing a heavy movable cylinder, allowing learners to investigate how internal mass distribution affects rotational motion and turning effects. By adjusting cylinder position, bottle dimensions, and initial conditions, students observe real-time changes in rolling behaviour, acceleration, and stability.

Learning objectives: Understand how the distribution of mass influences torque and rotational inertia | Analyse the relationship between turning forces and rotational motion | Predict and verify how internal mass movement affects overall bottle dynamics
