Frustration of the Day

Vagueness in sentence writing —

Awesome for literary fiction.

Horrific for science questions.

Dear Physics textbook writer and science professors who write my tests, please don’t half-ass your question phrasing. I’d like to know what you guys are actually asking before y’all start taking off points. You write, “What can you say about the motion of the Earth-Moon system about the Sun?” and expect me to answer:

“It is this Earth Moon CM location that actually traces out the orbit as discussed in chapter 5.The Earth and Moon will orbit about this location in (approximately) circular orbits. Themotion of the Moon, for example, around the Sun would then be a sum of two motions: i) themotion of the Moon about the Earth Moon CM; and ii) the motion of the Earth Moon CMabout the Sun. To an external observer, the Moon s motion would appear to be a small radius,higher frequency circular motion (motion about the Earth Moon CM) combined with a largeradius, lower frequency circular motion (motion about the Sun)It is this Earth Moon CM location that actually traces out the orbit as discussed in chapter 5.
