The student has identified a focused and detailed topic of investigation, clearly stating the research question and providing a breakdown of the IA. However, the research question could be more focused by specifying the range of values and unit of the independent variable, as well as using "to what extent" instead of "how" in the question tag. The physics concepts related to the topic are explained well, but the student is advised to include visualizations such as graphs or models. The methodology of the investigation is clear, easy to follow, and focused on addressing the research question. The student also demonstrates awareness of safety, ethical, and environmental issues.
