Uniform acceleration in relativity, #2/3

This is an attempt to describe acceleration (particularly uniform acceleration) in Einsteins relativity. Only special relativity will be used, but some phenomena associated with general relativity will be found. Check
http://www.phys.unsw.edu.au/einsteinlight/
for a basic intro to relativity. This is also partially a response to mooeypoo's Astronomy Simplified (#1): Basics of Time and Distance, http://www.youtube.com/watch?v=toTm9BrvHeo
, so check that out!

In the second episode, I start with length contraction and time dilations and go through how uniform acceleration is perceived by an outside observer.

Errata: At around 2 min, 30s into the clip, the equation should be a=a' (1 - v^2/c^2)^(3/2), not with a plus sign as in the presentation.

But you have read out the correct formula at 2:35.

Thanks for the tip! It is indeed incorrectly written in the visual presentation. I've put an errata into the video description. As there were similar issues in part 3, I'm thinking about making an updated version of part 2 and 3.

At 2:07 you have written a=a'(1+v²/c²)^(3/2) where it should read a=a'(1-v²/c²)^(3/2)
