Tracy's World - Stretched Slinky

Experiment with the Tracy Python activity by adjusting the sliders below. See how changing the circle size and forward distance affects the stretched slinky shape!

35
40

Tracy starts at the centerThe center of the grid (0, 0) of the grid, facing eastTo the right of the screen. She then:

  1. Draws a circleUsing the circle(size) command clockwise, starting and ending at the bottom of the circle.
  2. Moves forwardUsing the forward(distance) command to the starting point of the next circle.
  3. Repeats this process for each circle in the slinky.

Try adjusting the sliders to see how changing the circle sizeThis affects the radius of each circle and forward distanceThis changes the space between circles impacts the slinky's shape!

Python Code:

circle(35)
forward(40)
circle(35)
forward(40)
circle(35)
forward(40)
circle(35)
forward(40)
