Question
2) The velocity of a vibrating object changes as a function of time as v = - (0.6) cos[(2πs¯¹)t]. Represent this motion with a velocity-time and position-time graph Scientific Abilities Is able to construct new representations from previous representations Missing No attempt is made to construct a different representation. Inadequate Representations are attempted but use incorrect information or the representation does not agree with the information used. Needs Improvement Representations are created without mistakes, but there is information missing, i.e. labels, variables. Adequate Representations are constructed with all given (or understood) information and contain no major flaws. Represent this process with an energy bar chart for all key moments in time. Scientific Abilities Is able to construct an energy bar chart Missing No representation is constructed. Inadequate Bar chart is either missing energy values, bars drawn do not show the conservation of energy or are drawn in the wrong places. Bars could also be labeled incorrectly. The system is not identified. Needs Improvement Bar chart has the energy bars drawn correctly, but some labels are missing or the system is not identified. The bar chart matches the process described with some other representation. Adequate Bar chart is properly labeled and has energy bars of appropriate magnitudes. The system is clearly identified.
