M E C H A N I C S Introduction: Physics is the branch of science that deals with matter in relation to energy. Matter is anything that occupies space and has weight. There are three states of matter and these are i) Solids. ii) Liquids. iii) Gases. Energy is the ability to do work. There are different forms of energy and these are i) Heat energy. ii) Sound energy. iii) Light energy. iv) Chemical energy. v) Solar energy. vi) Nuclear energy. vii) Mechanical energy [kinetic energy and potential energy]. The above forms will be discussed later in this book. Career opportunities in Physics: A student who has done physics has the following career opportunities i) Electrical engineering. ii) Civil engineering. iii) Architecture. iv) Mechanical engineering. v) Geology. vi) Chemical engineering. vii) Astronomy. viii) Information technology. ix) Telecom engineering. x) Teaching physics. xi) Agricultural engineering. xii) Medicine. xiii) Phamarcy. xiv) Petroleum engineering Branches of Physics: Physics has the following branches; i) Mechanics. ii) Optics [light and waves] iii) Heat. iv) Electricity [Electrostatics and Current] v) Magnetism. vi) Modern physics.
