The aim of this post is to calculate the direction and speed of circular shaped bodies after an elastic collision. Explanations and demonstration are splited over the following pages:

- Part 1 - Hypothesys
- Part 2 - Velocity decomposition
- Part 3 - Velocity calculation
- Part 4 - Synthesis and reminder
- Part 5 - Source code
- Download Matlab script

The result of the model of an elastic collision between two balls:
