A project to help learn what makes it hard for a moving object to stop.
*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)
