A Run for Two
- Judah L Schwartz
RED and BLUE are on a circular track. Use the sliders to set their speeds. Sketch the separation between RED and BLUE as a function of time, when a) they are both traveling in one direction at different speeds b) they are traveling in opposite directions but at the same speed c) they are traveling in opposite directions at different speeds You can see an animation by clicking on the icon in the lower corner of either window. What are some questions you might pose to your students after they use this applet? What sorts of answers do you imagine getting when you ask those questions?
