Physics 213
Test #1
June 26, 2008
Name:______________________
This is a closed book test. You may use a calculator and a selfmade handwritten (no photocopying) crib sheet
of dimensions no more than 81/2” x 51/2” with any information on one side. For multiple choice questions,
circle the most appropriate answer. For problems,
show all your work!!!
Partial credit will only be awarded to
problems that include the steps used in arriving at the result. Take your time but pace yourself. If you haven’t
gotten to the long problems by the midpoint of the test, you should consider jumping to them and returning to
the other sections at the end. If a question is not clear, raise your hand, and I’ll try to clarify the question to you,
but don’t expect to get any hints. If you need more paper, I can provide you with some additional blank sheets.
Additional suggestions: If you cannot finish a problem write down what you do know and explain in words the
necessary steps. You will garner some partial credit for indicating the correct approach.
