-Watch the KEx and KEy values as they change with each collision, representing the total x and y kinetic energies of the particles. Kinetic energy is energy of motion. At the moment they strike it goes down, but after the strikes they go b
-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?).
The speed on the left is the red dots speed. The red seems to be moving and changing direction a lot faster and more often than the blue.
-Watch the 'blue' particle, and speculate on what property of this particle is different from that of the other particles.
The blue maintains a more consistent speed. It appears to change direction less easily than the red. It appears to have greater momentum.
-Watch as the 'red' particle sometimes turns yellow. What causes this? What property does the particle have when it is yellow?
I watched for over 5 minutes and it never turned yellow. I even recruited my wife to watch with me and we never saw it turn.
-What might the graphs represented at the right of the screen represent?
I'm not sure on this one. I would guess that it is average speed or KE by time between collision. I'm not sure though"
Good work. You can go on and do #3 in this experiment.
