orbits

Hey its Ant. Sorry for late post. Been busy with work and family matters. But any who recap of Friday's class.

Mrs. K gave us a wonderful new song to learn with lyrics. Inverse square law by Michael Offut. I will be getting Chris his CD for Christmas. Next we finished off the class with a video on Kepler's three laws. I learned a few things from this video such as Mar's orbit is actually an ellipse and not a circle, Kepler's three laws of, course. They are as followed :

1. r = ED/ 1 + cos θ
2. DA/DT = constant
3. T^2 = (4π^2/GM ) a^3

By the end of class she gave us 3 homework sheets. They are:
1. chapter 11 gravitational interactions
2. concept - development practice page 12-1
3. Universal law of Gravitation

don't forget your projects are due on Wednesday, Dec. 5...i think.
