====== Length Contraction ======

===== Prompts =====

** "Draw a diagram showing a meter stick on a moving train." **

** "Draw a diagram showing a meter stick at rest." **

** "Calibrate these diagrams using unit hyperbola." **

===== Context =====

//Estimated Time: 30 minutes, including wrap-up//

This [[strategy:smallwhiteboard:|SWBQ]] develops further understanding of
hyperbola geometry.  Students should know the basics of hyperbola geometry.

  * Length contraction is just the result of different observers making different measurements.
  * Spacetime diagrams can be calibrated using hyperbolas.

===== Wrap Up =====

  * Ask several students to present/defend their responses.
  * Construct right triangles with unit hypotenuse in both reference frames, emphsasizing the location of the right angle.
