assume you are checking that email address regularly.
b. If you have a cell phone you are willing to accept texts at, you can send
me that phone number in your email so I can send out a warning to you
when a change has been made to the problem set.
For the next two questions, I am relying on your previous experience in introductory
physics and in your ability to look at other resources online for help. If you use an online
resource, PLEASE cite it, but do NOT quote from it, use your own words!
3. At the beginning of the semester we will deal with gravity as a force. Later, we
will switch to using gravitational potentials. Can you provide a reason why
astronomers working with Galactic dynamics problems, such as the galaxy
collision simulation at http://www.youtube.com/watch?v=Cd9cBlvfjow, might
prefer to to figure out the motions of the stars by figuring out the gravitational
potential instead of computing the gravitational forces directly? Clearly explain
your reasoning. HINT: It might help to d...
