Physics is a natural science that focuses on the properties and behavior of matter, and the interactions between its fundamental constituents. This branch of physical science encompasses the study of all physical existence, from subatomic particles to the entire universe. It aims to define and understand the fundamental concepts and measurable quantities in the universe, such as velocity, electric field, and kinetic energy. Physics is described as the study of matter and energy, and how they interact with each other in the physical plane. It is considered to be an "awesome" subject that explores the laws and properties of matter and the forces that govern them in nature. Overall, physics is a broad and fundamental scientific discipline that seeks to uncover the mysteries of the observable universe.
