I worked on this with Aaron Holley
1. 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 of the red ball can be seen in the first number.
2. Watch the 'blue' particle, and speculate on what property of this particle is different from that of the other particles.
Watch as the 'red' particle sometimes turns yellow. What causes this? What property does the particle have when it is yellow?
The ‘blue’ particle moves slower than the other particles. It also seems to take more force to change direction. This could be because the blue particle is larger than the other particles or has some outer coating that causes more friction on the surface.
The ‘red’ particle turns yellow very infrequently. The only time that I have seen it yellow is when its speed is 8, I am not sure if it is 8 and above or if there is a range that it is yellow in.
3. What might the graphs represented at the right of the screen represent?
The graphs are very hard to understand. I am not sure what the blue dot graph is with the yellow box in the middle. The other two graphs look like histogram graphs. The top one looks like most of the data lies in the middle area. I am going to guess that it might be measuring the number of times certain speeds happen, so like a frequency vs. speed graph. The bottom graph has all of its data all the way to the left, I can not distinguish what this graph represents.
Good. No revisions are necessary, but see the discussion at the link given below.
