This Demonstration shows the deformation of a rotating square according to the Lorentz transformation from the frame of reference of a rocket (RFR) moving with a velocity . Beta () is the ratio , where is the speed of light, so goes from 0 to 1.

## Snapshots

## Details

Snapshot 1: a rotating cross with the RFR at rest ()

Snapshot 2: by increasing , the square changes shape

Snapshot 3: in the limit as , the square becomes a vertical line, according to the Lorentz contraction
