Your work has been received. Please scroll to the end of the document to see any inserted notes (in boldface) and a note at the end. The note at the end of the file will confirm that the file has been reviewed; be sure to read that note. If there is no note at the end, notify the instructor through the Submit Work form, and include the date of the posting to your access page.
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
Answer: average time between collisions is approximately 1 second with an average speed of 5.
• Watch the 'blue' particle, and speculate on what property of this particle is different from that of the other particles
The mass is larger from that of other particles.
• Watch as the 'red' particle sometimes turns yellow. What causes this? What property does the particle have when it is yellow?
When the red particle turns yellow it seems to be accelerating.
• What might the graphs represented at the right of the screen represent?
It might represent the change in speed with each collision.
• 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.
Good observations.
You should proceed to do #3 in the instructions.
