course phy202
Please advise which experiment you want me to run. I know this is out of sequence somewhat with the other assignments I've completed already but I had to wait since I couldn't get this to run properly at home on my mac.
My answers to the questions posed:-The KE values in each direction vary with time but seem to be roughly equal

- The left hand number at the top is the speed of the red particle
- I would speculate that the blue ball has much higher mass than the other particles
- The red particle turning yellow seems to happen when it accelerates to a very high speed.
- I think the histograms on the top and bottom of the screen might be either average KE for the particles divided into time windows/increments?
- The graph in the middle may be a dot diagram that shows the combined distribution of total combined KE both X and Y ? Not sure.
Very good. To be more specific, one of the graphs shows the frequency distribution of the velocities, the other of the kinetic energies. For a given velocity (or KE) on the horizontal axis, the corresponding vertical coordinate shows the relative freqeuency of that velocity (or KE). Since KE is the square of the velocity, the KE graph will have greater concavity; however the graphs otherwise appear very similar.
Go ahead and do experiment #3.
