experiment. Please let me know what to do next.
Also, I didn't see my Experiment 5 ""Current Flow and Energy""
posted on my portfolio page and I am wondering if I may have
submitted it without my name and access code which is 16-40-
907.
One last thing, I don't have the lenses in my lab kit to
perform Experiment 28: Image Formation; Combinations of
Lenses. And I'm a little unclear as to whether we are
actually to perform and write up experiment 28 or 27. If you
could send those materials to me, my address is:

Kinetic Model Preliminary Observations:
·Watch the KEx and KEy values as they change with
each collision, representing the total x and y kinetic
energies of the particles.
o It moves so fast I can? tell what the KEx and KEy
values are doing. The two values do not differ much from
each other. The stay within a 200-500 range.
·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?).
o The average time between collisions is about .25
seconds. The first speed corresponds to the red particle.
Its average speed is about 4 cm/sec.
·Watch the 'blue' particle, and speculate on what
property of this particle is different from that of the
other particles.
o The blue particle has a greater mass which is why it
moves more slowly and other particles bounce off of it.
·Watch as the 'red' particle sometimes turns yellow.
What causes this? What property does the particle have when
it is yellow?
o The red particle is moving extremely fast when it
turns yellow, so maybe it has to do with acceleration.
·What might the graphs represented at the right of
the screen represent?
o Maybe they are related to the velocities of the red
and blue particles.
·Strike the 'S' key to stop the simulation, and if
you are done give the appropriate response to the prompt to
quit the program. CTRL-ALT-DELETE will also stop the
program, but if you're not careful it will reboot your
computer so avoid that option if you can.
