Time Dilation & Space Contraction: I'm Confused

Click For Summary
SUMMARY

The discussion centers on the confusion surrounding the application of time dilation and length contraction equations in the context of special relativity. The user initially misapplies the equations t=γ*t0 and L0=γ*t, leading to an incorrect conclusion about velocity. The clarification provided emphasizes the necessity of using the full form of the Lorentz transformation to accurately relate these concepts. Ultimately, the user acknowledges their misunderstanding and expresses gratitude for the assistance received.

PREREQUISITES
  • Understanding of special relativity concepts, including time dilation and length contraction.
  • Familiarity with the Lorentz transformation equations.
  • Basic knowledge of physics terminology, such as eigen time and reference frames.
  • Ability to interpret mathematical equations in the context of physics.
NEXT STEPS
  • Study the full form of the Lorentz transformation to grasp its implications in special relativity.
  • Explore the derivation of time dilation and length contraction formulas from the Lorentz transformation.
  • Learn about the implications of constant velocity in relativistic physics.
  • Review common misconceptions in special relativity to enhance understanding.
USEFUL FOR

Students of physics, educators teaching special relativity, and anyone seeking to clarify concepts of time dilation and length contraction in the context of Lorentz transformations.

I'm confused. If t=γ*t0 and L0=γ*t how does the equation x=v*t hold for x0=v*t0, for constant velocity (Let t0 be the time in the stationary reference frame and t the moving frame, the same for length)? Then v would be equal to γ^2*v... Perhaps I'm missing something here.

Would you please spend some time proof reading your post and editing it to remove all typos and grammatical errors? Also, please make sure your equations are really what you want them to be and it would help if you would define all your variables.

I don't think I did commit grammatical errors in my OP. Maybe you mistaked to (eigentime) with the word to (preposition). I should have used italics, my bad.

The time dilation and length contraction formulas you wrote are special cases of the Lorentz transforms, not the general case. You need to use the full form.

I see. I have looked deeper into it and I seem to have sorted it out. My initial assumptions were incorrect. Thanks for the help.
