## 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 muon 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 Proton analogy. So what? There's an equation. How do I use the equation in the game? Practice Problems. Examples to aid your practice. Examples to aid your practice? Example 1: If you were to board a craft and travel at 0.9 c and were 6 feet tall, how tall would you appear to the earth's reference frame? Example 2: A muon travels 10,400 km in the earth's reference frame when it travels at 0.998 c. How far does it travel in its own reference frame? Example 3: A craft is observed to be 25 meters long when at rest on the earth. It passes you and appears to be 15 meters long. With what velocity does the craft travel? 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.
