The student demonstrates a clear understanding of the physics focused on in the essay, providing extensive and relevant descriptions of variables. Additionally, the student appropriately references and incorporates sources relevant to the research question, including necessary definitions for content outside the IB syllabus. However, the student missed including physics-specific measurements alongside appropriate units, and the integration of annotated diagrams in an efficient manner to advance the communication of physics in the essay needs improvement. Nonetheless, the student consistently and clearly identifies symbols in the context of the situation and applies appropriate and precise physics terminology throughout the essay.
