Spring Controller Demonstration

The simulation illustrates how a spring controller acts as a soft constraint, allowing two rigid bodies—a ring and a disc—to interact through elastic collisions. By visualising the spring’s restoring force, students can see how energy is stored and released during the impact, linking the concepts of work, energy, and momentum conservation.

Students can watch the motion of the objects in real time and observe live graphs that plot kinetic, potential, and total energy throughout the collision. The display of rigid bodies, joints, and energy curves helps learners connect the abstract equations of work‑energy principles to concrete visual behaviour, reinforcing their understanding of elastic collisions and constraint forces.
