Introduction:
Any change in velocity requires a force. When this force is steady, the feeling can be compared to gravity. By controlling the rate of change of velocity, the "Gs" can be adjusted.

Activity:

 * Watch the video clips at this link:

 * Think about the activities that you will put in the spinning ring of your Space Hotel!

Conclusion:
The curvature of the Earth is so gradual that we barely notice it. In a spinning structure, the curvature could be very noticeable!

Practice:
One of these movies got the science wrong! Can you tell which one, and explain why? Hint: It has to do with the windows and the "floor"!
