About this Simulation

This interactive simulation models two spring forces acting simultaneously on a point mass. Learners adjust force magnitudes and directions using adjustable poles and bases, visualising how individual vectors combine to produce a resultant force. Real-time vector diagrams show the geometric relationship between component forces and their sum.

Learning objectives: Understand vector addition graphically and algebraically | Determine resultant force magnitude and direction from two component forces | Explore conditions for equilibrium when multiple forces act on a point
