For best results always work out the practice problems first. Once you have worked these out you can check the solutions to make sure you completely understand the concepts and problems. Then you will have a better understanding of what is going on with the assigned homework problems. Reading and working through the relevant section in the Study Guide before tackling the problems to hand in should also help a lot.
For each problem the following should be included:
A sketch of the physical situation.
Knowns and unknowns.
The fundamental formulas from which the calculation begins.
Intermediate algebra steps.
Substitution of numerical values (including units) at the end of the problem.
Correct units on your answers.
It is expected that collected problems will have to be worked out on scratch paper and then a final presentation of the solution made on a separate piece of paper. Solutions should be in a straightforward, logical sequence.
Collected problems should have your complete name written in the upper right hand corner of your paper.
Late assignments will not be accepted. Assignments are due at the beginning of each class period in the front of the classroom.
A note on grading: you are not graded on your answer, you are graded on your solution. For example, if there is no sketch or the steps in the middle are hard to follow, you won't get full credit even if the final answer is right.
When writing out your homework solutions, include not only the diagrams and equations which lead to the answer, but elaborate on the reasoning that led you to the steps in your answer. Think of the good and bad examples your various physics texts have presented you with. Write your homework problems like the good ones, and remember how frustrating those “the remainder is an exercise left to the reader” passages have been.
