Activity: Possible Worldlines

Theoretical Mechanics (4 years)
Student consider several curves on a spacetime diagram and have to judge which curves could be worldlines for an object.
What students learn
  • Speed on a spacetime diagram is inverse slope.
  • Object can't travel faster than the speed of light.
  • Lightlines have a slope of 1 (when axes are scaled to the same units)
