Physics is a fundamental branch of science that explores the nature and properties of matter and energy. It delves into the behavior of matter under various conditions, and the interactions between different physical entities. From the smallest building blocks of matter, like atoms and subatomic particles, to colossal celestial bodies, physics seeks to understand the underlying principles that govern the universe. By applying mathematical models and theories, physicists can explain a variety of phenomena, ranging from the mundane to the extraordinary.
