I noticed something strange
Posted: Mon Sep 05, 2016 6:25 pm
I did a little experiment, and i noticed something odd about the collective velocities of two objects bouncing in a room.
What I did:
I turned off gravity and air friction
I created four planes, which formed a small room.
I put a box and a circle in said room.
I made the planes, box, and circle have zero friction and 1 restitution.
I moved around the box and circle so they would be bouncing around, never losing energy.
The weird part:
I selected both of the objects and got a plot of them.
I selected velocity x over velocity y.
I noticed that the graph was only showing 90* or 180* turns, bending at right angles.
When i dragged the box, however, the graph showed squiggly meaningless readings.
When i let go of it, it started moving only at right angles again.

Any mathematical reason why this would happen?
