Introduction:
Now that you had a week to play, it is time to get down to business. Hopefully you are
aware of the class requirements and are ready to go on to bigger and better things. Unit 2
prepares you to start doing some physics. For most people the scariest part of physics comes
when they have to use the math that seemed so useless to this point in their lives. Physicists
use math as their language--it is the easiest and clearest way to state an idea. Isaac Newton
developed calculus, because he needed it to solve physics problems. You don't have to use any
calculus here, but you will need to do some algebra , trig, and graphs. |
