University Physics I Equation Sheet and Homework and Test Instructions
It is imperative that your work be
neat
and
clear
.
To receive full credit for a problem, your work must convincingly
demonstrate that you understand the physics behind that problem. This means not only providing the correct answer but
also showing how you obtained your answer. There should always be a symbolic expression for any formula. The symbolic
equation is what you should manipulate, then, substitute in your numbers, with units. Report final answers with correct
units and vector expressions. There should be enough English to give the reader some idea of what you are doing without
looking at the math, and the diagrams need to be big enough (and neat enough) that they can be clearly read.
