Fizika, or physics, is the branch of science that studies matter, energy, and the fundamental forces of nature. It explores how objects move, interact, and change, providing a framework for understanding the physical universe. Key concepts in fizika include force, motion, energy, and waves. Fizika is divided into several subfields, such as classical mechanics, which deals with the motion of objects, and quantum mechanics, which focuses on the behavior of particles at the atomic level. Through experiments and mathematical models, fizika helps explain everyday phenomena, from why the sky is blue to how electricity powers our homes.
