Unformatted text preview: the response, the student • uses an appropriate method that reflects a basic understanding of three of the four major concepts or that reflects a good understanding of two of the major concepts • gives formulas and/or diagrams that are implicitly correct; however, they are not applied to determine the final solution or errors in the application of equations are present, but the answer is consistent with calculated results 3 In the response, the student • uses an appropriate method that reflects a basic understanding of all four of the major concepts or that reflects a good understanding of three of the major concepts • uses an appropriate method that reflects an excellent understanding of two of the major concepts and that reflects a basic understanding of one of the two remaining concepts • uses formulas and/or diagrams that may be implicit, and these are applied correctly; however, errors in calculations and/or substitutions that hinder the understanding of the physics content are present • provides explanations that are correct but lack detail • has a major omission or inconsistency 4 In the response, the student • uses an appropriate method that reflects a good understanding of all major concepts or that reflects an excellent understanding of three of the major concepts • provides explanations that are correct and detailed • states most formulas explicitly and applies them correctly • makes minor errors, omissions, or inconsistencies in calculations and/or substitutions; however, but these do not hinder the understanding of the physics content • draws most diagrams appropriately, correctly, and completely • may have errors in units, significant digits, rounding, or graphing 5 In the response, the student • uses an appropriate method that reflects an excellent understanding of all major concepts • provides a complete description of the method used and shows a complete solution for the problem • states formulas explicitly • may make a minor error, omission, or inconsistency; however, but this does not hinder the understanding of the physics content • draws diagrams that are appropriate, correct, and complete • may have an error in significant digits or rounding Physics 30 – January 2000 iv February 8, 2000 Sample Response • Determine the direction of the magnetic field needed to cause protons to circle in the direction shown. Justify your answer. The direction of the magnetic field is from the lower magnet to the upper magnet. This direction is determined using the right hand rule for positively charged particles in a magnetic field. The thumb indicates the direction of the proton’s & velocity, v . The palm (or bent finger) indicates the direction of the magnetic force, Fm . The fingers (or index finger) indicates the direction of the upward & magnetic field, B . or & The fingers indicates the direction of the proton’s velocity, v . The thumb & indicates the downward direction of the induced magnetic field, B . Apply...
