The student's essay title accurately reflects the aim of the investigation and is presented as a statement, not being the same as the research question. Early in the essay, the student outlines the research area, purpose, and focus, establishing the context of the research question. Relevant physics principles are identified, and a formal development of the theory follows later in the essay. The student effectively addresses the research question with chosen methods and materials, justifying their decisions. The rationale for choosing experimental methods is clearly explained without being dominant in the essay. Additionally, the essay is data-based and incorporates reliable and appropriate literature research. However, the consideration of uncertainties and limitations of apparatus is lacking.
