25.2 Time Dilation and Length Contraction | Relativity | General Physics

Chad provides a thorough lesson on Time Dilation and Length Contraction, two major points of the Special Theory of Relativity. For observers that are moving very fast (close to the speed of light) time slows down and lengths (or distances) contract in the direction of motion. Chad derives the time dilation formula, including the derivation of the Lorentz factor, and uses that to also derive the length contraction formula. Great emphasis is placed on how 'proper' time and 'proper' length or distance are defined and specifically from which observer's perspective. Several time dilation and length contraction problems are then solved using these formulas.

So grateful that you're still teaching all these years later, Chad. You helped me in organic chem back when I took it in 2017, and now viewing your videos for the MCAT :) - literally indispensable. Please keep doing what you do

[@ChadsPrep]

Glad the channel continues to help you - Best in your MCAT studies!

What is the formula of velocity when there is time dilation and length contraction simultaneously due to speed and gravity?

[@muhammadaslamsoomro5287]

Sir your teaching way is absolutely charming ❤🎉🎉💕 and thanks for uploading beneficial lectures for us bundle of thanks my dear sir.
