The average time between collisions = 1 or 2 seconds
The average speed = 5 or 6
Observing BLUE ball:
It seems larger and probably heavier, because collisions do not seem to affect it as much. It does not change direction drastically and its speed does not increase or decrease by much. There is also more time between collisions than the red ball.
RED ball turns YELLOW:
The cause of this is when a yellow circle collides with the yellow ball. After collision with the yellow ball, the red ball with the yellow circle around it goes much faster. As soon as it collides with a plain circle, it returns to just plain red.
GRAPHS:
I think these graphs may represent different velocities or energies. Each line represents a velocity or energy and everytime a collision occurs a new line is formed.
I went ahead and completed EXPERIMENT 3.
** As the particles start colliding the direction of the particles goes from primarily in the x-directions to the x- and y- directions. The particles start scattering and going in all different directions rather than just in the x-direction.
** The x and y Kinetic Energies start high in the x KE and low in the y KE. As time goes on the y KE gets higher and the x KE energy starts to get lower. As more time passes they just continue to go back and forth on eachother.
** The system is more organized at the beginning of the simulation because most of the particles are going in the x-direction but then they all start going in all different directions.
** I think that if the x and y kinetic energies were averaged for 100 years they would probably pretty much even eachother out. The more data you have the more accurate your calculation will be...So I am thinking if you have more Kinetic Energy measurements, the difference between the x and y will be very VERY small.
** The average for my x KE = 553.9133. The average for my y KE = 612.18.
** The difference in the averages is not significant. There is a difference between the two, but i do not believe they are significant. I think it is probably just because the balls started out going in the x direction and did not have a good amount of time to randomize. "
