The particles on the screen start out with a very high KEx and a very low Key. When particles collide, they change direction, so when the trial starts with a high Key, when the particles collide, a lot of them change directions and travel in a more vertical direction.
As the trial goes on, the particles become less and less organized in that KEx and KEy even out and each particle has a different direction than other particles.
If I were to average KEx and KEy over 100 years, I would expect them to be exactly even, or extremely close since KEx is much greater than KEy for the first few seconds. But I don’t think it would have an effect if the experiment runs for 100 years.
I conducted 10 trials and on average it took 7 seconds for the KEy to first be greater than KEx.
The average after thirty collections of data using the fast setting, is KEx=373.5 and KEy=371.7. These answers are very close. This data supports the fact that over 100 years, the KEx and KEy will be virtually equal.
