Use an on-line simulation from the University of Colorado PhET group to review motion in one dimension.
Link to the simulation: http://phet.colorado.edu/en/simulation/moving-man
Explore the interface!
Try the different tabs at the top of the simulation.
To produce graphs under the Charts tab, use Pause, set the parameters using the sliders, press Clear, and then press Play.
Use the controls on the bottom to Pause, Step, Record and Playback the motion.
Select Record before you start an experiment if you want to save it.
On the Chars tab, the vertical gray lines in the charts can be grabbed in Playback mode to help you to relate the graphs to the man's motion.
Mathematical Expression and Reverse axis are advanced features under Special features.
Now go to Canvas, Assignments, Extra Credit 2. Use the simulation to help you answer questions 1 - 5. You can submit twice and the highest score counts.
