This week's office hours

The units covered on Dr. Nero's next exam are: Newton's Laws, Circular Motion, and Work/Energy. I have been stressing to the students that for any type of problem that could appear on the upcoming exam, it is important to draw a diagram to aid in understanding the question. I find that I make far fewer mistakes when I draw a diagram and write down applicable equations, even though neither the diagram nor some of the equations will be necessary for every question.
