Homework Help: Does my weight change if I travel

  1. Mar 12, 2010 #1
    1. The problem statement, all variables and given/known data

    Does my weight change if I travel near the speed of light?

    2. Relevant equations


    3. The attempt at a solution

    What do you think will happen as you approach speeds near or at the speed of light?

    My mass will increase, but I am not certain if weight increases.

    My hunch is that I won't notice anything in my frame of reference. What I mean is, nothing will change - my weight will stay the same.

    Is that right?

    I don't know too much on relativistic calculations, but weight is associated with gravity, so assuming you can approach c for a certain 'g', your weight will increase.

    But if you are flying through space, in your frame, I would agree with you.

    Okay, thank you very much. It's probably not crucial to include frame of reference.
