Physics

Physics is the Natural Science that studies matter, its motion and behaviour through space and time, and that studies the related entities of energy and force. Physics is one of the fundamental scientific disciplines, and its main goal is to understand how the universe behaves.  Physics is the branch of Science concerned with the nature and properties of matter and energy. The subject matter of physics, distinguished from that of chemistry and biology, includes mechanics, heat, light, and other radiation, sound, electricity, magnetism, and the structure of atoms.
