The student identifies a focused and detailed topic for the investigation, exploring the relationship between impact velocity and the coefficient of restitution of a tennis ball dropped onto a tennis racket. While the research question is articulated, it lacks the definition of the independent variable range and a brief explanation of how the dependent variable is calculated. The physics concepts are well-explained, making them easy to understand, and the methodology is clear, structured, and directly addresses the research question. Additionally, the student demonstrates awareness of safety, ethical, and environmental issues related to the procedure, ensuring a comprehensive approach to the investigation.
