Bzp05M.jpg


Now you're in other space.No gravity at all.You 're going to make your own artifical gravity R = 100m
Quest
1-) With which angular velocity, g is equal to 10 (g = 10)
2-)Can you walk from b to a? Why is that
3-)Can you walk from b to d? Why is that
4-)Can you walk from c to d? Why is that

My Solution

a=w^2.r
10=w^2.100
w=0.301 this one first question.
2-3-4 questions
I think The resulting gravity is towards the center.therefore only walking from b to d.But I could not prove

Note:Sorry !! If you have spelling error I don't know English.I use Google

According to Physics Forums rules, you need to make an attempt to solve the problem before we can offer help. What are your thoughts on the problem?

My apologies for posting possible solution before OP made fair attempt at it.
Brain not in gear...

Remember, it is not really gravity.. it is just some perceived force that feels like gravity.
If you are inside a rotating drum, what force do you perceive?
How does the direction of gravity relate to one's ability to walk?

With regard to walking from c to d, was the arrow in the diagram given to you or did you add that? Is that the only route?

Yes, I just need to examine C to D for this rotation.
I think,No because artifical gravity in A.Can only come to A . We can't walking. Am I true ?

So what routes should you consider?
artifical gravity in A.Can only come to A .
I have no idea what that means.
Please try to answer this question:

You don't need Google, you just need to think.
When you walk, what is the direction of gravity in relation to the direction in which you walk?
Would it be difficult to walk with some other relationships?

hmm... actually....

If you walked fast enough you could go through a cross corridor, counting on residual velocity to keep you glued to the "floor", both to and from the axis.

Getting started would be the problem.

Yes, that answers my first question in post #10. What about the second one?
I understand you ,can you explain a little more in Question 2

Can you walk up a wall? Why not?

I think that , you can just walk from B to D
