Referring to the below information from a previous submission... if we are in a situation without a gravitational field, what would be a quality of the blue particle to make it behave as it does in the program? Is that program written to assume we are in a gravitational field?
What do you think are the average velocities of the 'red' and the 'blue' particles and what do you think it is about the 'blue' particle that makes is so? end of document
The program assumes no gravitational field. The only interactions are between the particles and between particle and wall.
If there was a gravitational field, say downward, then the paths of the particles would be concave-down parabolas and there would be a tendency toward greater concentration of particles lower on the screen. If the gravitational effect was small (corresponding to high particle velocity and a small distance scale) these effects would not be readily apparent (e.g., curvature would be very slight and differences in concentration would have to be established by statistical analysis of a large number of position observations).
