Analytic Question Scoring Guide

(5 marks each)
Check before you submit your work:

Did you state the relevant physics principles as stated on your physics data sheet?
Did you state the equation from the equation sheet?
Did you show the manipulated form of the equation?
Did you show the substitution and units?

Did you calculate the correct final answer and paraphrase the answer with the correct significant digits and appropriate units?

Scoring Guide for Analytic Questions

Physics Principles

Score	Description
4	Both relevant physics principles are stated and both are clearly related to the response. Physics principles for questions involving linear vector addition require explicit communication of the vector nature; e.g., a situational diagram or a free-body diagram (FBD) for forces and a vector addition diagram.
3	Both relevant physics principles are stated, but only one is clearly related to the response.
2	Both relevant physics principles are stated but neither is clearly related to the response. or One relevant physics principle is stated and is clearly related to the response.
1	One relevant physics principle is stated.
0	No relevant physics principle is stated.

Substitutions

Score	Description
1	All substitutions are shown. Significant digits are not required in intermediate steps. A response with at most one implicit unit conversion may receive this score. An incomplete or incorrect response may receive this score if all the values substituted are appropriate; i.e., length measurements into length variables, energy measurements into energy variables.
0	Too many substitutions are missing. or The response contains one invalid substitution; i.e., electric field strength for energy or speed for electric potential difference.

Formulas

Score	Description
3	All relevant formulas required for the complete solution are present and have been written as they appear on the equations sheet or in the information given with the question.
2	Most relevant formulas are stated. or Derived formulas are used as starting points.
1	One relevant formula from the formula sheet is stated.
0	No relevant formula is stated.

Final Answer

Score	Description
2	The value of the answer to the complete problem is stated and calculated consistently with the solution presented. The final answer is stated with the appropriate number of significant digits and with appropriate units. A response in which an inappropriate substitution has been made may receive this score if the incorrect units are consistently carried forward.
1	The value of the final answer is stated, calculated consistently with the solution presented. Units or significant digits are incorrect. or The response is incomplete, but an intermediate value is stated and calculated consistently with the solution presented with appropriate units (significant digits not required).
0	The answer stated is unrelated to the solution shown. or No answer is given.
