Physics is a natural science that involves the study of matter and its motion through space and time, along with related concepts such as energy and force. Physics aims to describe the function of everything around us, from the movement of tiny charged particles to the motion of people, cars, and spaceships. In fact, almost everything around you can be described quite accurately by the laws of physics. The study of physics is capable of making significant contributions through advances in new technologies that arise from theoretical breakthroughs. In architecture, physics is at the heart of structural stability and is involved in acoustics, heating, lighting, and the cooling of buildings. Physics has many applications in the biological sciences. On the microscopic level, it helps describe the properties of cell walls and cell membranes.
