A project to help learn what makes it hard for a moving object to stop.
*v2.1 REMIXED from expert graphs model. Increasing range of data boxes to cover cases from worksheet. added toggle for showing graphs
*v1.4 removed x position data box; set up challenge to add linear graph of x position of all three turtles vs. time
*v1.3 remove sliders for ?t and braking force; add data box to report stopping positions for each turtle
*v1.2 adding a grid to give an outcome variable so students can make quantitative comparisons.
*Fixed glitch where there were initial settings that don't stop the turtle before the end (increased the breaking force to 395)
*stop the simulation after 200 ticks
Glitches still to fix
**there are initial settings that don't stop the turtle when v<0
Things I'd like to implement:
*Each turtle reports its stopping distance (numerical value; for now, visually might be good enough)
