Dutch (DQ) and Engl...

On the very same quiz, Question #8 asks the students to choose a vector diagram that most closely represents the gravitational forces that the earth and moon exert on each other. The three most popular choices are shown in the figure below. There are a number of issues that always arise, implicitly or explicitly, when conducting quantitative research and carrying out data analysis in Physics Ed...
