Physics is the natural science that studies matter, its motion, and behavior through space and time, and that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, and its main goal is to understand how the universe behaves.
Physics is divided into two main branches: classical physics, which studies the behavior of matter and energy in the macroscopic world; and quantum physics, which studies the behavior of matter and energy in the microscopic world. Classical physics includes mechanics, heat, electricity and magnetism, light, and sound. Quantum physics includes atomic and subatomic physics, condensed matter physics, nuclear physics, and particle physics.
Physics is essential to the understanding of how the universe works. It has been integral to the development of essential technologies like the telephone, television, computer, and the Internet. Physics is also involved in important medical applications like MRI and CAT scans, and in the development of new materials and energy sources.
Fizikia ni sayansi ya asili ambayo hujifunza mambo, mwendo wake, na tabia kupitia nafasi na wakati, na ambayo hujifunza vitu vinavyohusiana vya nishati na nguvu. Fizikia ni mojawapo ya masomo ya msingi ya kisayansi, na lengo lake kuu ni kuelewa jinsi ulimwengu unavyofanya kazi. Fizikia imegawanywa katika matawi mawili: fizikia ya kawaida, ambayo hujifunza tabia ya vitu na nishati katika ulimwengu wa makroskopi, na fizikia ya quantum, ambayo hujifunza tabia ya vitu na nishati katika ulimwengu wa microscopy. Fizikia ya kale inatia ndani mitambo, joto, umeme na sumaku, nuru, na sauti. Fizikia ya quantum inajumuisha fizikia ya atomu na subatomic, fizikia ya dutu iliyofupishwa, fizikia ya nyuklia, na fizikia ya chembe. Fizikia ni muhimu kwa kuelewa jinsi ulimwengu unavyofanya kazi. Imekuwa sehemu muhimu ya maendeleo ya teknolojia muhimu kama vile simu, televisheni, kompyuta, na Intaneti. Fizikia pia inahusika katika matumizi muhimu ya matibabu kama MRI na CAT scans, na katika maendeleo ya vifaa vipya na vyanzo vya nishati.
