I'll elaborate. This year, in high school I started studying physics for the first time ever - I know, Mexico's Educational System is one of the Worst :\ - And I really, really liked it. The thing is, right here in mexico it is really hard to make a living as a physicist, and It's really...

I think I get what you say. So, since the elevator is in free fall, so are the objects, accelerating at the same speed, Which means they're bot moving downwards, so there's no Normal force acting on the scale. Is that right?

Homework Statement Well, that's all, my mid-term exam came a question that asked me: if a body with mass of 50 kg was weighed on a scale that is inside an elevator in free fall, how much will it weight? I supposed that the same it would weight on the surface, since gravity never stops...

You mean this question: "CHALLENGING pHYSICS questions(dedicated for lover's of physics)" 'Cause if so, I'm totally trying to solve that one, right after my Physics exam on Friday (Today :D ) It seems interesting, mainly because I'll have to read some old stuff, as well as some new stuff to...

Wow! Thanks, It seems a little more logical hehe :P And it makes sense, since I'm studying Newton's 3 laws of motion. Thanks :)

Homework Statement This problem is regarding Friction Force: Imagine a skateboard, low and with well-oiled bearings. What would happen if, standing over it at rest, you begin to walk along its length? The Attempt at a Solution There are 4 options. I chose this one: It would start moving in...
