PPT-Electric Charge and Static Electricity

Electric Charge All matter is made up of atoms Atoms contain Protons Neutrons 0 Electrons Law of Electric Charges The law of electric charges states that like charges repel and . Electric Charges. Electrons . can. . move. from one atom to another, but protons . cannot. move .. When an atom has . gained. electrons, it has more electrons than protons, and it is . negatively. Introduction to Electricity. Let review…. All matter is made up of atoms.. Atoms are made of charged subatomic particles.. Electric charge is a fundamental property of matter, similar to mass.. The electromagnetic force exists between protons and electrons. Like charges repel. Opposite charges attract.. Lesson . 2. :. Sparks (part 2). There are two types of charge. What are they?. An atom has four protons and five neutrons. How many electrons has it?. Friction produces static charge. How?. With reference to the last question. Why?. WHAT IS STATIC ELECTRICITY?. . Static. . electricity. is . a. . FIELD FORCE . – . it. . can. . act. . over. . a. . distance. .. It. is . generated. by . FRICTION. .. The. . Van der . Graff. How Static Electricity Builds Up. When substances gain or lose electrons, we say that they are electrically charged.. Items, such as plastics can easily become charge with when they are rubbed very quickly with a woollen cloth.. It’ll shock you!. What is Electricity?. The movement of charges (electrons). Can be passed (current). or Stationary (static). Electrostatics. = the study. o. f static electricity. Differences?. Static Electricity: . Static . Electricity. A . buildup of . electric charge. . on an . object.. Does not flow through wires. “Static” means . “not moving”.. . May . “jump”. . from one object to another. . Matter is made up of tiny particles called . A . force. is a push or pull exerted on an object.. Energy. is the ability to do work or cause change.. Potential energy . is the stored energy that results from the position or shape of an object.. Examples of electrostatic discharges. Lightning . . – static cling in dryers. “foot dragging” – “shocking” cats. Electrical charges come in two types, and –. Amber (Gk. electron) is associated with – . 7.1: Static Charge/Electricity pp. 228. Refers to electric charges that can be collected and held in one place.. “static” means stationary or not moving. Is the temporary transfer of electrons (e-).. All Matter is Made of Atoms. Atoms consist of a nucleus made of particles called protons and neutrons, orbited by electrons. Atoms are Electrically Neutral. Atoms have the same number of protons ( ) and electrons (-) and have no charge. Mary Tweedy, Curriculum Support Specialist – Science.
