Study Notes
Special Relativity and Lorentz Factor
- The Lorentz factor represents the time dilation effect in special relativity
- It is related to the speed of light in a vacuum
- When an object moves at a significant fraction of the speed of light, time in the moving frame slows down
- If an object moves at half the speed of light, the Lorentz factor (γ) for this motion is 1.15
- An astronaut traveling at 0.8c relative to Earth will experience time dilation, experiencing 0.6 hours for every Earth hour that passes
- For a particle accelerating to a velocity of 0.9c, the Lorentz factor (γ) for this motion is 2.3
- Two spaceships, A and B, moving relative to each other at 0.6c, experience time dilation
- If a clock on spaceship A records 10 minutes, a clock on spaceship B will record 8 minutes and 20 seconds due to time dilation
