The Beach Ball JavaScript Model simulates the dynamics of a thrown beach ball. Because of its relatively low mass (compared to its size), subtle effects that are important in sports like baseball, soccer and volleyball become exaggerated in the beach ball's motion. This simulation allows users to explore a simple model of several "complications" to simple projectile motion: drag, buoyancy and the Magnus effect. Drag slows the ball down, buoyancy makes the ball "float" and the Magnus effect puts a curve on the ball's trajectory.
The Beach Ball JavaScript Model was developed using the Easy Java Simulations (EjsS) version 5. It is distributed as a ready-to-run html page and requires only a browser with JavaScript support. It is also distributed as an ePub.
