As depicted in the picture. Sorry, I have minimal experience with physics at all lol, but my paint game is strong right? It is a 1 kg object with the center of mass perfectly in the center, rotated 90 degrees in 0.1 seconds. What about in 1 second? http://imgur.com/OIOdZ6f http://imgur.com/OIOdZ6f How much force (in Newtons) would it take for 0.1 seconds or 1 second? Would it make a difference if the object is falling/suspended? With/without gravity? Is there any difference Position 1->2 vs Position 2->1? Relevant equations would be great too, and they'd probably answer multiple (if not all) of my questions at once.
