Elastic collision - Equations and simulation

Introduction and summary

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:
