The Secondary 3 Physics curriculum is designed to help students develop a deeper and more comprehensive understanding of concepts such as forces, energy, and waves, which were briefly introduced in Secondary 2 Science. One key difference between Secondary 2 Science and Secondary 3 Physics is that in Physics, there is a stronger emphasis on mathematics. Students are expected to use their mathematical skills to solve complex problems related to physics concepts. Overall, Secondary 3 Physics requires a higher level of complexity and depth of understanding compared to Secondary 2 Science.
