What is  Physics  Physics is the branch of science which deals with matter and its relation to energy. It involves study of physical and natural phenomena around us. Examples of these phenomena are formation of rainbow, occurrence eclipse, the fall of things from up to down, the cause of sunset and sunrise, formation of shadow and many more. Physics as a subject is divided into six broad branches as discussed below. i) Mechanics This branch deals majorly with motions under the influence of forces. Under this branch, we look into details the aspects of linear, circular and oscillatory motions as well as motion of fluids ii) Geometrical Optics This branch takes a keen look at the behavior of light in various media. iii) Electricity and magnetism This branch looks at the interaction between electric fields and magnetic fields and the applications of such interactions. iv) Thermodynamics This branch looks at how heat as a form of energy is transformed to/from other forms of energy. v) Atom
