Representing Motion on Speed-Time Graphs – Comparing motions of multiple objects
Imagine, for a moment, that four aliens (Kinet, Modulus, Terek and Stas) visiting earth were involved in creating various motions.

These motions are represented in a simulation. Watch the simulation movie below. Pay attention to the speed arrows for each of the four aliens.
