Centre of Mass of the Earth, Sun and Mars
Think about the situation described below. A number of questions based on this situation are posed afterwards, each having 2 possible responses (FALSE or TRUE). We'll do some (but probably not all) of these questions in the lectures when you will all be asked to vote on which answer you think is correct. (Soon afterwards, you'll be able to see your responses, and those of the whole class at EVAF.)
