A.3Methodological considerations
Moderate
Criteria Feedback
- The student framed the investigation in a specific and relevant physics context, which makes the aim clear and manageable.
- The student identified several important methodological factors such as launch angle, frame rate, air conditions, and repeat trials.
- The student's equipment list and overall sequence show that they had a workable plan for collecting data.
- The independent variable is not operationally central in the method, because compression is named but not actually varied.
- Some procedural details are missing, so another person could not fully reproduce the investigation without ambiguity.
- Several methodological choices are stated but not fully justified in terms of how they affect data sufficiency and validity.

Criteria Feedback
- The student's tables and worked calculations make the processed data easy to follow.
- The student consistently uses units and uncertainty notation, which improves clarity.
- The student applies the relevant kinematic and energy relationships in a mostly appropriate way for the model they are using.
- Repeating the calculation across trials and averaging the result is a sensible way to improve reliability.
- The raw evidence for all trials is not shown as clearly as it could be, so the reader cannot verify every processed value easily.
- Some uncertainty values are not well justified, and they are not propagated through to the final result.
- The graph does not add much new evidence because the plotted quantities are derived from the same equation used in the calculations.
- There are some conceptual issues in the interpretation of the energy values, especially at the peak of the motion.
