This energy can take the form of motion, light, electricity, radiation, gravity etc. Physics deals with matter on scales ranging from sub-atomic particles (i.e. the particles that make up the atom and the particles that make up those particles) to stars and even the entire galaxies. It can also be defined as a natural science that involves the study of matter and its motion through space-time, as well as all applicable concepts, such as energy and force. More broadly, it is the general analysis of nature, conducted in order to understand how the universe behaves. <\/p>\n<p>\u00a0Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Over the last two millennia, Physics had been considered synonymous with Philosophy, Chemistry, and certain branches of Mathematics and Biology, but during the scientific revolution in the 16th century, it emerged to become a unique modern science in its own right. However, in some subject areas such as in mathematical physics and quantum chemistry, the boundaries of physics remain difficult to distinguish. <\/p>\n<p>\u00a0Physics is both significant and influential, in part because advances in its understanding have often translated into new technologies, but also because new ideas in Physics often resonate with other sciences, Mathematics, and Philosophy. For example, advances in the understanding of electromagnetism or Nuclear physics led directly to the development of new products which have dramatically transformed modern-day society, such as television, computers, domestic appliances, and nuclear weapons; advances in thermodynamics led to the development of motorized transport; and advances in mechanics inspired the development of calculus.<\/p>\n<p>\u00a0In order to understand clearly the fundamental concepts, Physics is divided into two main branches: <\/p>\n<ol>\n<li>\n<div>Classical Physics \u2013 This consists of the following: mechanics, heat, optics, wave and sound, electricity and magnetism.\n<\/div>\n<\/li>\n<li>\n<div>Modern Physics \u2013 This covers the aspects of matter energy and their relations at atomic and sub-atomic levels.\n<\/div>\n<\/li>\n<\/ol>\n<p>\u00a0Other fields of Physics are: Geophysics, Astrophysics, Bio-physics, Nuclear physics, Engineering physics etc. <\/p>\n<p>\u00a0<strong>EVALUATION<br \/>\n<\/strong><\/p>\n<ol>\n<li>What do you understand by the term &#8220;Physics&#8221;?\n<\/li>\n<li>\n<div>State the step involved in scientific method?\n<\/div>\n<p>\u00a0<strong>FUNDAMENTAL QUANTITIES AND UNIT<br \/>\n<\/strong>Measurements play an important role in Physics. A unit has to be defined before any kind of measurement can be made.  Different systems of units have been used in the past. These include the foot \u2013 pound \u2013 second (FPS) system, the centimetre \u2013 gramme \u2013 second (CGS) system, and the metre \u2013 kilogramme \u2013 second (MKS) system. The new system which has now gained universal acceptance is the systeme international d&#8217;units, usually called S.I. units.<\/p>\n<p>\u00a0Physical quantities are often divided into fundamental quantities and derived quantities.<\/p>\n<p>\u00a0<strong>FUNDAMENTAL QUANTITIES<\/strong>:<br \/>\nThese are the basic quantities that are independent of others and cannot be defined in terms of other quantities.<br \/>\nThey are the basic quantities upon which most (though not all) quantities depend.<\/p>\n<p>\u00a0<strong>FUNDAMENTAL UNITS<\/strong>: are the basic unit upon which other units depend. They are the units of the fundamental quantities.<br \/>\nThe three most important basic quantities in Physics are length, mass and time.<\/p>\n<p>\u00a0<strong>Length<\/strong> may be defined as the extent of space or distance extended. <\/p>\n<p>\u00a0<strong>Mass<\/strong> is commonly defined as the quantity of matter or material in the body. <\/p>\n<p>\u00a0<strong>Time<\/strong> is defined as that in which events are distinguishable with reference to before or after.
