ATOMIC PHYSICS The nuclear atom All matter is made up of atoms which consist of a central nucleus‚ surrounded by electrons. Inside the nucleus are protons and neutrons. Particle Relative mass Charge Location Proton 1840 + Nucleus Neutron 1840 0 Nucleus Electron 1 - Outside nucleus Proton or atomic number (Z) This is the total number of protons in the nucleus of an atom. Nucleon or mass number (A) This is the total number of protons and neutrons in the nucleus of an atom. Note: a nucleon

Plasma Complexity! Plasma is said to a substance similar to gas in which a certain portion of the particles are ionized. The basic premise is that heating a gas dissociates its molecular bonds‚ rendering it into its constituent atoms. Further heating leads ionization‚ turning it into plasma: containing charged particles‚ positive ions and negative electrons. The presence of a non-negligible number of charge carriers makes the plasma electrically conductive so that it responds strongly to electromagnetic

Characteristics and Nature of Waves In physics‚ a wave is a disturbance that travels through space and time‚ usually accompanied by the transfer of energy. Waves travel and the wave motion transfers energy from one point to another‚ often with no permanent displacement of the particles of the medium—that is‚ with little or no associated mass transport. They consist‚ instead‚ of oscillations or vibrations around almost fixed locations. For example‚ a cork on rippling water will bob up and down

The type of physics that I will be presenting is a branch of Fluid Mechanics. Fluid mechanics studies the physics of gases and liquids. Hydraulics is defined as: "a branch of science that deals with practical applications of liquid in motion." Merriam-Webster’s Medical Dictionary‚ via www.dictionary.com The science started over thousands of years ago with Aristotle (384-322 B.C.) and Archimedes (287-212 B.C.). Many European scientists also contributed to hydraulics‚ including

The Physics of Baseball The sport of baseball has been around for over two hundred years‚ roughly since the 1800s. Invented by a man named Alexander Cartwright. It is known as “Americas past time.” Baseball is the national sport of the USA. The first baseball game played was in New York on June 19‚ 1845. And is played by thousands of people throughout the years. Much like any sport‚ it has changed with time. The first rulebook of baseball was issued in 1877. And it has been changing every year

In 1916‚ Henri Fayol published his "14 Principles of Management" in the book "Administration Industrielle et Generale." Fayol also created a list of the six primary functions of management‚ which go hand in hand with the Principles. Fayol’s "14 Principles" was one of the earliest theories of management to be created‚ and remains one of the most comprehensive. 14 Management Principles developed by Henri Fayol are : 1. Division of work : Work should be divided among individuals and groups
