Class 16, ICA #15, September 30.

There were 2 clicker questions. There were 2 total marks possible.
We did do a lecture-tutorial on Kepler's second law but 
clicker questions about it happened on October 2 instead.

You get 1 mark for answering each question.
I didn't count getting it right or not.
The clicker questions count for a total of 3 points toward your
course grade, so your points for the day = # of marks * (3/2).




Clicker Question #1: Which orbit (if any) is not real?

B.


Clicker Question #2: At which point or points is the
planet speeding up?

E. points I and III.
