Length contraction:
A meter-stick appears longest to an observer who is at rest relative to it. An observer moving relative to the meter-stick at v observes the stick to be shortened by a factor of γ.
\gamma=1/\sqrt{1-v^2/c^2}

1. In the garage's frame of reference, the bus is moving, and can fit in the garage (for observer at rest with the respect to the garage).
2. In the bus's frame of reference, the garage is moving, and can't hold the bus (for observer moving with the bus).

Try to play with the following simulation and have fun with relativity! Smiley

  • Please feel free to post your ideas about how to use the simulation for better teaching and learning.
  • Post questions to be asked to help students to think, to explore.
  • Upload worksheets as attached files to share with more users.
Let's work together. We can help more users understand physics conceptually and enjoy the fun of learning physics!
