·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?).
There was less than a second between collisions.
The middle speed corresponded to the red particle, which was changing between 1-10.
· Watch the 'blue' particle, and speculate on what property of this particle is different from that of the other particles.
Its speed is much slower, its mass is much greater, and probably its temperature is much lower.
· Watch as the 'red' particle sometimes turns yellow. What causes this? What property does the particle have when it is yellow?
As it accelerated to its maximum speed, it turned yellow.
It has increased kinetic energy, increased temperature, and increased acceleration.
· What might the graphs represented at the right of the screen represent?
They may represent the total kinetic energy.
&#Good responses. Let me know if you have questions. &#
