## Lesson 1: Relativity - What is it? 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 pole and the barn analogy. 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. Question Answer Choice b - 6.93 years: Excellent work! You got it. All it takes is realizing that the time for the mover by the stationary frame, t, is 8 years. The time for the mover by the mover, to, is what we want to determine, and the relative velocity is 50% c, or 0.50 c. The work I did is shown below and should have been similar to yours! Back to Alpha Centuri example Lesson 3: Length Contraction The equation. Where does that come from? I still don't get it! Give me the Alpha Centuri example. So what? There's an equation. How do I use the equation in the game? Practice Problems. Examples to aid your practice.
