Physics 914 MCQs [All-Courses]

Physics is a core science subject that deals with the study of matter, energy, motion, force, heat, light, electricity, magnetism, and modern physics concepts. It plays a vital role in competitive exams such as PPSC, FPSC, NTS, OTS, KPPSC, BPSC, AJKPSC, CSS, and PMS, where questions test conceptual understanding, numerical problem-solving, and application of laws and formulas.
