Inquiry-Based Physics Exam Solutions
Course Introduction
Inquiry-Based Physics is an innovative course designed to engage students in the active exploration of physical concepts through hands-on investigations and critical thinking. Rather than relying solely on traditional lectures, this course emphasizes the process of scientific inquiry, encouraging students to formulate questions, design experiments, collect and analyze data, and draw meaningful conclusions about the physical world. Students develop conceptual understanding in areas such as motion, forces, energy, and waves, while also enhancing problem-solving skills and collaborative abilities. By focusing on discovery and the scientific method, Inquiry-Based Physics cultivates a deeper appreciation for how physics shapes everyday experiences and advances technology.
