Fermilab's Time Dilation Challenge. The Basics of Relativity (6 seconds) The Relativity Game - Challenge what you know! Note: For Fermilab's Time Dilation Challenge and The Relativity Game, you need Shockwave. You may painlessly Download Shockwave here if you do not have it. Lesson 2: Time Dilation The equation. Where does that come from? I still don't get it! Give me the basketball analogy. So what? There's an equation. How do I use the equation in the game? Practice Problems. Examples to aid your practice. Lesson 3 : Length Contraction The equation. Where does that come from? I still don't get it! Give me the Alpha Century Example. So what? There's an equation. How do I use the equation in the game? Practice Problems. Examples to aid your practice. Lesson 4 : Relativistic Mass The equation. Where does that come from? I still don't get it! Give me the space pool analogy. So what? There's an equation. How do I use the equation in the game? Practice Problems. Examples to aid your practice.
