Scribe Post #3

Well since there looks like there has been a slump in the scribing over the last couple of days I think this is a good time to finish up my last scribe post.

Today in class we started off by getting back our Circular Motion & Work and Energy tests. We then went over the answers with Mrs. K and made sure we had the correct answers.

We then moved onto watching a video. The name of it was "Kepler's Three Laws." After watching that and answering the question sheet, we went over the correct answers for that.

"Kepler's Three Laws."

1. Each planets path is an ellipse and each planet moves around the sun which is called the focus.

2. The imaginary line from the sun to a planet sweaps out equal areas in equal time intervals. Planets move faster when closer to the sun and slower when farthest from the sun.

3. The ratio of the squares of the periods of any two planets revolving about the sun is equal to the ratio of the cubes of their average distances from the sun.

The video took the greater part of the class and we were left with about 20 minutes to finish up Study Guide 8. Also those who missed the lab yesterday were given time to finish that up.

That was it for today and i'll see you guys all back in class tomorrow.
