  I know, but where is it??? That's the one that I sent in to take the real one.

  I can't find the test itself, just what you found. I want the test again.

  Do these questions look good?

     for someone that just wants a simple mind f'in on gravity.......

             Take a sheet of paper and drop it. See how it falls like a leafish type free fall and then....

             Take a heavy book bigger than that mo' f'in leaf lookin' like a piece of lazy fallin' paper.

                                Not factoring in the variables of miniscule differences in controls (ain't no such thing).....put that paper flat on the book with no flappin' f'in edges.

                Paper on top of that book when you drop it level as you can hauls ass just like that book to the gravitational question of "What the.....What?"

             Bricks, Feathers, Ohhhhhh.    

                     I just thought about opening a dark mass helium balloon outpost.

                Nobody givin' up secrets.

  I knew these "Puzzled" threads were truly just about trying to figure out what the fook Texas Dave was thinking/saying...just needed the clarification.  Now I feel better.

  I think that's to do with air pressure. Because the book and paper are moving through the air at speed and a book isn't very aerodynamic. A low pressure area is created directly behind the book. A higher pressure area is behind the paper, and because the air pressure behind the paper is higher than the air pressure between the paper and the book, the paper gets pressed against the book.
  
  A little like cycling along behind a bus. The air pressure between you and the bus is lower than the air pressure behind you, so you get pulled along.

      In theory....Gravity affects everything at the same rate of speed after dropping. With no wind resistance, feathers and paper and bricks and books tie in a vacuum.

  Unless, of course, you're talking about WGT virtual golf balls, in which case, you're lucky to get them to drop at all.

  In earth's atmosphere, the bag with the tonne of feathers would take longer because of the wind resistance: it's a much bigger bag.

  On the moon, with no atmosphere and thus no resistance, they would land at the same time (indeed, even if they didn't weigh the same amount).

  Yes they do. Some. However, it was a timed exam, I had to have certified by a local college.

  I see the man that was receiving these papers for grading, stopped quite a while ago.

  I don't agree with the way IQ is graded with these tests. Genius is a curse, ask one.

  Open book IQ tests now??

  Any way, taking the test you sent, (TY very much) I seem to have developed a little. Then I took another one, just for comparisons sake. I mistakenly slipped on a banana peel.

  I will have to try a third.

  Thanks for finding that for me.
