Kinetic Lab Preliminary

course Phy 232

Watch the KEx and KEy values as they change with each collision, representing the total x and y kinetic energies of the particles. 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?).

It seems as if the speed of the red ball is represented with the first number.

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?

It looks as if the ‘blue' particle moves slower than the other particles. It also looks as if when the blue particle collides with other particles it responds less than the red particle. The blue particle could be larger or have more mass than the other particles causing these effects. It looks as if the red ball turns yellow the faster it moves, I think that is what is causing it to turn yellow.

What might the graphs represented at the right of the screen represent?

These graph are difficult to decipher because they are not labeled. The graphs appear to be some kind of spread of the speed and the number of particles traveling that speed. I cannot fully figure out what the graphs actually are though.

Good. No revisions are necessary, but see the discussion at the link given below.
