Physics 247 Homework

Physics 247 fall 2007
Homework

You will learn physics by solving problems. There is no other way.

Homework grading policy

Each week, 4 problems will be chosen at random to be graded. Submitted problems are graded on a 10-point scale as to whether they were Complete (3 points), Clear (2 points), Plausible (1 point), Initially OK (1 point), and Correct (3 points). Several of the problems will be graded in discussion by students grading other students (peer review). The Rubrics for assigning peer review grades is as follows:

Complete
3 = all parts present and fully developed
2 = some parts incomplete
1 = major sections missing
0 = little meaningful work done
Clear
2 = model (i.e. physical reasoning) was clear to the grader
1 = some aspects were unclear
0 = model was completely opaque
Plausible: One point was awarded if the result's magnitude, sign, and/or units were plausible.
Initially OK: One point was awarded if the solution was acceptable on the first pass
Correct
3 = no modeling or algebraic errors
2 = some modest errors were made
1 = fundamental errors were made
0 = almost nothing was correct

Larry will grade two homworks each week and the grading will bebased upon the following rubric:

Homework 1: Interactions: C1B.5, C1S.2, C1S.3, C1S.4; C2B.2, C2B.9, C2S.2, C2S.3, C2A.1

Homework 2: Vectors, momentum transfer, particles and systems: C3B.2, C3B.4, C3B.5, C3B.7, C3S.2, C3S.6, C3A.1; C4B.1, C4B.5, C4S.3, C4S.5, C4S.8, C4A.1
