That is what I cannot reconcile with. The astronauts in the space shuttle, when orbiting earth, would not be able to step on a scale. That makes perfect sense. Thank you again for your time.

Thank you. That helps. Hypothetically speaking, if I stepped on a scale, then the scale would read zero, because there is no gravitational pull while traveling in a ship near the speed of light?

This is a general question, not requiring an equation. If I travel near the speed of light, I know my mass will increase. I am assuming my weight will increase, but since there is little gravitational pull, since I am not near any large objects, then my scale would say near-zero, if I stepped...

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

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? Thanks.

Homework Statement Does my weight change if I travel near the speed of light? Homework Equations NA The Attempt at a Solution NA

Thank you.

Homework Statement Does an object, like a rocketship, physically contract when traveling near the speed of light? Homework Equations NA The Attempt at a Solution Not a mathematical question.

That's perfect. Thanks!

Unless the other guy was also 200 lbs, right?

Yes, it is momentum, I believe. I read that if two objects crash into each other, then they bounce off each other - and that is not a complete stop. However, it seems that the mass of both objects would need to be equal, as long as the velocity is equal. Is that right?

Homework Statement A runner has a mass of 168 Kg and is traveling North at 5 meters per second. Another runner is traveling South at 5 meters per second. They collide and come to a complete stop. What is the mass of the second runner Homework Equations I do not have an equation...
