Physics is a natural science that explores the fundamental principles governing the universe, from the smallest subatomic particles to the vastness of space. As a course, physics involves studying concepts such as motion, forces, energy, waves, electricity, magnetism, thermodynamics, and modern physics (including quantum mechanics and relativity).  

A physics course typically includes both theoretical and practical components. Students engage in mathematical problem-solving, laboratory experiments, and real-world applications. The subject requires strong analytical skills and a solid foundation in mathematics, especially algebra and calculus.  

Physics is essential in many fields, including engineering, medicine, astronomy, and technology. It helps develop critical thinking, problem-solving abilities, and an understanding of how the universe functions.
