The Fascinating World of Physics

Physics is all around us. From the moment we wake up and switch off our alarm clocks to the time we go to sleep at night, physics plays a role in everything we do. But what exactly is physics? Simply put, physics is the branch of science that deals with the nature and properties of matter and energy. It explains how things move, why they fall, how electricity works, and much more.
