Objectives:  How does nuclear fusion
in the sun release energy?
Announcements: Journals Friday
Opening Data:  Speed o' light,
c = 3 x 10⁸ meters/second
670 million miles/hour

7 times around the earth in a second

1.5 seconds to travel to the moon

8 minutes to the sun  

Where does all the energy come from

in nuclear interactions?  

4.3 x 10¹² g lost by the sun each second through nuclear fusion 

What energy is equivalent to
that?  

Don't forget!! Reflection is
due tomorrow.
