I'm not exactly sure how this part of the experiment got left out in my mind. I'm so sorry!
Experiment kinmodel_03: Equipartition of energy and the direction of disorder to (increasing or decreasing)Observe the first several seconds of the simulation at the 'slow' default speed. You will see how the particles initially are all moving in or very close to the x direction, with little or no y component. Note the x and y kinetic energies, displayed near the top of the screen.
Observe what happens to the directions of motion of the particles as they start colliding.
Observe what happens to the x and y kinetic energies.
Is the system more organized at the beginning of the simulation or after a couple of minutes?
If the x and y kinetic energies were averaged for 100 years, starting a few minutes after the simulation began, which do you think would be greater?
Run the simulation in this manner several times, and each time determine how long it takes before the total y kinetic energy is first greater than the total x kinetic energy. Report your results.
Now take some data:
Running at the fastest default speed, stop the simulation with the pause/break key every few seconds, keeping your eyes closed for at least 2 seconds before stopping the motion.
Write down the x and y kinetic energies each time.
Do this at least 30 times.
Find the average of all your x and all your y kinetic energies.
Do you believe the difference in the averages is significant, in that the direction that has the higher average will always tend to have the higher average every time the simulation is run?
######## The direction of the particles begins to randomize after they start moving for more than a few seconds.
######## The start as mostly moving in the X direction, and then move in the Y direction too. This begins after a few seconds have passed and particles are randomly colliding.
####### The system appears more disorganized as time goes by.
####### I believe after that much time, they averages would be about the same because the system is so random once collisions start. . Most likely not the exact same number, but possible give or take 20% or so.
#######
X:343.42
Y: 380.76
#######
I dont believe so, only because the system is very random, and even my coordination could create an average with different values each time.
&#This looks good. Let me know if you have any questions. &#
