Week 2 Assignments

1) Read Chapter 2 in your Classical Mechanics text for class on Wednesday.

2) Review material in the Mathematics Companion. This week, we will use material from 1.5, 1.6, 1.7, and 1.9.

3) Watch and work through in matlab our video on Leapfrog integration.

4) Homework #2 is due 1/25/17 4pm in Jiajie Xiao's mailbox in Olin 100. It is:

A) Problems 1.8, 1.9, 2.5, 2.6, 2.8 from your text

  •  2.8 should be considerably more difficult than the other problems.
  • Hint: this integral table might be of use.

B) Using the leapfrog and Euler-Cromers integrators, redo the computational problems from HW #1 and comment on the differences between Euler, Euler-Cromers and Leapfrog in terms of the steps needed.

 

  

 

Homework #1

The first homework for the course. 

A few points:

1) plots have labels and titles.

2) don't pick an initial condition that results in no motion.

3) When asked to comment on what changes, discuss how the modeling of the motion varies with timestep for the two different cases including comparing the time steps needed for different force laws and the specified accuracy.

Here are the expectations for writing up homework assignments.

Week 1 Announcements and assignments

This week, Jan 11 and 13th, we will focus on reviewing Newton's equations and introducing Matlab as a tool for solving problems in classical mechanics.

Your assignments:

1) Read Chapter 1 in your Classical Mechanics text. Ideally in time for class on Wednesday but absolutely in time for class on Friday.

2) Install Matlab on your laptop and make sure it runs. You can obtain it at software.wfu.edu . If you have difficulty installing Matlab, go to the Bridge. Make sure you have an working copy by class on Friday.

3) Review material in the Mathematics Companion. In particular, we will use material from 1.1, 1.3, 1.4 this week, along with 2.1.1. However, next week, we will use material from 1.5, 1.6, 1.7, and 1.9, so I encourage you to review ahead.

4) Watch, and work along with in Matlab, our introductory video on Matlab before class on Friday. 

5) Watch our video on Leapfrog integration. We might not get to until next week, and it might be a little challenging, but go ahead and watch it now first before class on Friday.

Our first homework will not be due until the 18th.
