GUIDELINES AND STUDY TIPS FOR QUIZ 1 ON MAR 30/2010
1. Please bring a calculator No books or notes are allowed.
2. For the quiz, expect a mix of long and short questions. The
questions will test conceptual understanding, a few will
require you to work though simple algebra
3. The quiz can include material covered in class up to the last
lecture on orbits (Th Mar 12), as well as related material
in the books. An expanded class syllabus is on
http://www.as.utexas.edu/~sj/a381c-sp10/a381c-sp10-outline.txt
Below are some study tips from the syllabus. Note, however, that
these tips are not exhaustive and the quiz may include some items
that are not listed below:
For section (II) Important Timescales
a) you should know the significance of the timescales, how to use
them, and know typical numbers for different stellar systems
galaxies, stellar clusters, etc
For section (III) Newtonian Dynamics and Potential Theory
a) For spherical potential, you should know the expressions for
Potential Phi (e.g., Eq 9 on lecture of Tu Feb 9), the
Gravitational force F, circular speed Vc, Escape speed Ve,
and total Potential energy W
b) For spherical potential, if given density rho(r), you should
know the 3 methods to get potential Phi(r), as discussed in
the solution for homework problem 2.3 :
- Use Force times Distance to get work done
- Integrate Poisson's Equation
- Use the summation of shells at r'
