Which experiment number should I complete for Assignment 5 according to my observations?
Preliminary Observation* Watch the KEx and KEy values as they change with each collision, representing the total x and y kinetic energies of the particles.

The note at the end of the file will confirm that the file has been reviewed; be sure to read that note. If there is no note at the end, notify the instructor through the Submit Work form, and include the date of the posting to your access page.
* Watch the 'red' particle for a couple of minutes, estimating the average time between its collisions and its average speed (one of the speeds given near the top of the screen corresponds to that of the 'red' particle--which is it?).
Red particle speed is about 5, and the time between collisions is anywhere from 1 to 4 seconds.
* Watch the 'blue' particle, and speculate on what property of this particle is different from that of the other particles.
It is heavier and therefore it is slower and harder to move when it has a collision with another lighter particle.
* Watch as the 'red' particle sometimes turns yellow. What causes this? What property does the particle have when it is yellow?
The red turns yellow when a yellow cirlce collides with it, but it turns red again as soon as it collides with another particle. So it must be some sort of transfer of energy or something.
* What might the graphs represented at the right of the screen represent?
I do not have any graphs at the right of the screen.
I think the graphs represent the length of time between collisions. Each line's length corresponds to the number of seconds between collisions."
Good work. Let me know if you have questions.
