# Linear Collision of Two Disks

Requires a Wolfram Notebook System

Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.

This Demonstration shows the linear collision of two disks, with varying masses, velocities and coefficients of elasticity. The velocity vectors of the disks A and B are shown before and after impact by red and green arrows, respectively. The velocity is positive when left to right. The velocity versus time plot includes a collision region that is modeled using the tanh function to simulate real experiments. In all cases, the total momentum of the two disks is conserved.
