About Course

Physics is the fundamental science that seeks to understand the fundamental principles governing the behavior of the universe, from the smallest particles to the vast cosmos. It explores the nature of matter, energy, space, and time, aiming to uncover the underlying laws and forces that dictate how everything in the universe interacts and evolves. Physicists utilize mathematical models, experiments, and observations to formulate theories that explain natural phenomena, enabling technological advancements and deepening our comprehension of the cosmos. The study of physics encompasses a wide range of subfields, including classical mechanics, electromagnetism, thermodynamics, quantum mechanics, relativity, and cosmology, each contributing to our ever-expanding understanding of the intricacies of the physical world.
