PPT-Section 1: Electric Charge and Static Electricity

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. 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. 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.. 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 circuit is formed when an electric current passes through an unbroken path of conductors. . 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. Keisha Kidd, Curriculum Support Specialist – Science.
