Problem Set Instructions & Rubric

Objective:

Demonstrate your understanding of physics principles by applying conceptual knowledge, mathematical reasoning, and problem-solving strategies to a set of assinged problems.

Instructions:

  1. Read Each Problem Carefully: Identify what is being asked, what information is given, and what principles apply.
  2. Draw Diagrams When Applicable: Include free-body diagrams, motion diagrams, vector diagrams, or circuit diagrams as needed.
  3. List Knowns and Unknowns: Clearly identify given quantities (with units) and the values you need to find.
  4. Select Relevant Equations: Choose appropriate formulas based on the concepts involved (e.g., Newton's Laws, kinematics, energy conservation, etc.).
  5. Show Algebraic Work: Rearrange formulas symbolically before substituting numerical values to demonstrate your understanding.
  6. Perform Calculations With Units: Substitute values carefully, showing each step, and ensure all final answers have proper units and appropirate significant digits.
  7. Write a "Therefore" Statement: Conclude each solution with a clear "Therefore" sentence that directly answers the question asked. Round to the correct number of significant digits and include appropriate units and direction where applicable.

Problem Set Rubric

  • To achieve Level 3 or 4, be sure to use diagrams, show clear steps, and always include a "Therefore" statement that directly answers the question with proper units, significant digits, and direction (where applicable).
  • This rubric will be applied to each problem set in this course unless otherwise noted.

Category Level 1 (50–59%) Level 2 (60–69%) Level 3 (70–79%) Level 4 (80–100%)
Knowledge Demonstrates limited understanding of relevant physics concepts; frequent inaccuracies Demonstrates some understanding of relevant physics concepts with several errors Demonstrates considerable understanding of physics concepts with minor errors Demonstrates thorough and accurate understanding of relevant physics concepts
Thinking Applies strategies with limited effectiveness; equations or logic often incorrect Applies strategies with some effectiveness; occasional errors in reasoning or setup Applies strategies and formulas effectively; mostly accurate and complete Applies problem-solving strategies and formulas with a high degree of accuracy and insight
Communication Work is unclear or disorganized; diagrams or “therefore” statements are missing or incorrect Work is partially clear; diagrams or final statements may be incomplete or inaccurate Work is generally clear and organized; diagrams and “therefore” statements are present Work is consistently clear, well-organized, and effectively communicates the solution
Application Frequently inaccurate or incomplete application of formulas, units, and sig. digits Some correct application; may have issues with rounding, units, or interpreting results Mostly correct application of physics to solve problems; minor errors in units or sig. figs Consistently applies physics accurately; all units, sig. digits, and directions are correct
