About this Simulation

This simulation models the dynamics of two stacked blocks subjected to an applied horizontal force. Learners can investigate whether the blocks move together or slip relative to each other by adjusting the applied force, friction coefficients, and block masses. Real-time force vectors and acceleration data reveal the physics underlying contact forces.

Learning objectives: Determine conditions for static friction versus slipping between objects | Analyse normal and friction forces in multi-body systems | Apply Newton's second law to predict block motion and interaction
