PPT-Electrostatics and the Electric Field

1 When the balloon is rubbed on the sweater what might happen A Some positive charges in the sweater will move onto the balloon B Some negative charges in the sweater will move onto the balloon. Conductors. Prof. Hugo . Beauchemin. 1. Introduction. We have seen most of the powerful concepts needed to understand electrostatics. W. e now turn to concrete applications, solving the equations. we saw for various types of system encountered in experiments . How do you find the area of a triangle?. This was the most missed question on the test…. DO WORK. STOP. Objectives. Investigate the majesty of electricity so you can soon control lightning like Zeus.. October 2012. Objectives.. To understand the basic properties of electric charge.. To describe the difference between conductors and insulators.. To calculate the electric force using . Coulumb’s. Law.. Examples of Electrostatics in the world are. :. A doorknob shock. Static in the dryer. Your hair standing up when combed. What is electrostatics? (644). Electricity at . rest. Involves electrical charges, the forces between them, and their behavior in materials. Units of Chapter 16. Static Electricity; Electric Charge and Its Conservation. Electric Charge in the Atom. Insulators and Conductors. Induced Charge; the Electroscope. Coulomb’s Law. Solving Problems Involving Coulomb’s Law and Vectors. Essential Knowledge. 1.B.2. : There are only two kinds of electric charge. Neutral objects or systems contain equal quantities of positive and negative charge, with the exception of some fundamental particles that have no electric charge.. 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 – . Science and Mathematics Education Research Group. Supported by . UBC. Teaching and Learning Enhancement Fund . 2012-2015. Department of . Curriculum and Pedagogy. FACULTY OF EDUCATION. Question Title. . Electric Potential (Energy). Charges. The fundamental rule at the base of all electrical phenomena is that . like charges repel and opposite charges attract. An object that has unequal numbers of electrons and protons is . EDII Section 1. Continuous medium with ions and electrons. Average potential. Some external electric field. 1. Macroscopic electrodynamics: fields in space occupied by matter. Spatially average the actual microscopic field over atomic length scales.. Charges are conserved. Charges are additive in nature. Charges are quantised.. PROPERTIES OF ELECTRIC CHARGES. PRODUCTION OF ELECTRIC CHARGE. We can get electric charge by three ways. By friction or rubbing. 1.B.2. : There are only two kinds of electric charge. Neutral objects or systems contain equal quantities of positive and negative charge, with the exception of some fundamental particles that have no electric charge.. Coulomb's Law : . Coulomb's Law states that the force between two point charges Q. 1. and Q. 2. is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.. charged and how does . a charged object . affect other objects . in its vicinity?. What makes up all matter?. What does it mean to be “charged”?. What is GROUNDING?. What are insulators & conductors?.
