Elastic collision between two particles with variable velocity and mass:

Two particles (num 1 blue, num 2 red) can be dragged to a given position in the simulation window.
The last clicked particle is the current particle (can also be switched in 'Particle nr ...').
To the left of 'Particle nr ...' the color of the current particle is shown.
Velocity information for the current particle can be set / or is shown in 'vx', 'vy' and 'v'.
Mark the checkboxes if the velocity vectors should be shown.


Control objects:
