More on those 3 Laws...

An example of using math to find out something that would be impossible otherwise...(or maybe you are thinking it is the math that is impossible :p!

Weight, if you will recall, is a measurement of the effect that gravity has on an object.  Mass is how much matter an object has.  Calculate your weight in Newtons. (See page 77-78.   If you don't know your own weight in kilograms, multiply your weight in pounds by 2.2.  1 kilogram = 2.2 pounds.)  Write your weight ( in Newtons) in the comments.

 Watch these lecture videos on Newton's 3rd Law: 
Newton's 3rd Law- Derek Owens  -- Watch the 4 sections Chapter 2.7 a-d

Read textbook pages 83-85 and answer the multiple choice questions on this  3 laws worksheet:  http://www.jbgrimes.myclassupdates.com/sitebuildercontent/sitebuilderfiles/newtonsthirdlawws.pdf


Also, finish the 2nd page of the worksheet from class.
Now that you are really smart, here is some rocket science--

  2. 2156 N. Yaaaaaaaay!!!!! Jenna and I weigh the same in Newtons!!!!!!!!! My brother did the math for me because I was confused about how to convert Kilograms into Newtons, so I hope he did it right.
