Two-tracks animations

Click below to view the "realistic" and "unrealistic" animations of balls rolling on sets of tracks that were used for the student tasks in Tom Thaden Koch's dissertation.

There are four sets of animations, presented (sequentially) on six web-pages:
  1. One-ball Flat-valley animations.
  2. One-ball V-valley animations.
  3. Two-ball Flat-valley animations.
  4. Two-ball V-valley animations.
  5. One-ball and Two-ball Flat-valley animations (to compare your one-ball and two-ball choices).
  6. One-ball and Two-ball V-valley animations (to compare your one-ball and two-ball choices).
Try to identify the animation from each set depicting the most realistic motion before moving on to the next set of animations. The animations within each set can be played at regular speed or in "slow motion" by clicking on numbered buttons.

Go to the first set of animations.
