    I'm not following you, Fizziks. None of the graphed values (k∆x vs. Msinθ) are theoretical. k - must be calculated somehow, based on measurements of force, displacement, and/or the like ∆x - measured M - measured θ - measured sinθ - calculated What theoretical values are you referring to?

    Graphing k∆x vs. Msinθ would result in a slope of g. Not a slope of 1. But since k must have been calculated, the wording of the rubric makes it sound like this solution wouldn't count.

    A very interesting question, OP. Color me flummoxed.

    I'm looking at the AP Mech C practice FRQ: https://apclassroom.collegeboard.org/29/question_bank/create/preview/item/1320757 On part c, the scoring rubric says "1 point is earned for [graphing] a pair of quantities that could be used to determine g - students must graph measured, not calculated quantities." Does this mean that graphing k∆x vs. Msinθ would not earn the point? If so, that would deviate from past AP Exams, would it not?
