Downbearing?

Hi Julia

This is 2nd year highschool math and 1st year highschool physics. Not 
more.  At least here in Norway. In the US, perhaps a year behind.
Cheers

Greetings,

       (See below) This is so Greek to me! Where does one learn to 
calculate
such things. Recommended reading would be appreciated!

Thanks
