Center of Mass System
This interactive simulator explores Center of Mass System in Classical Mechanics. 2–4 bodies or rod: R_cm, V_cm; explosion with ΣΔp = 0; |P| and |V_cm| graphs. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.
Who it's for: Best once you already know the basic definitions and want to build intuition. Typical context: Classical Mechanics.

How it works
Several point masses (or two on a massless rod) move in a frictionless box. The center of mass and V_cm are drawn; total momentum and |V_cm| stay constant when you apply the symmetric internal “explosion” (ΣΔp = 0). Elastic walls change individual momenta but not P_tot.
