Relativity Train
[XL | t++ | ★★★★]
Demonstration of time dilation and length contraction gedanken experiment using a train on a track.
Bouncing Photon
[XL | t++ | —]
A photon (modeled by a bouncing ping-pong ball) is observed from two reference frames and provides the motivation for time dilation.
Faraday Induction
[M | t | ★★★]
Reference frames: equivalence of moving the magnet and moving the coil is shown.
