Collision simulation with Python, vPython and NumPy

The simulation in this video was made using Python as programming language. For the visualization, it was used the VPython library and for the data processing, NumPy.
The algorithm emulated a fluid flow carrying wood logs of 10 ft. All the physics of the collisions are took into account and are calculated by the algorithm (drag force, angular momentum due to the collisions, impact force, and others).
