In this Chapter we will the force acting 2007–2008 Workshop Materials Special Focus: Electrostatics 3 A Note from the Editor Peggy Bertrand Oak Ridge High School Oak Ridge, TN One of the most di cult areas of physics to learn, and 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.. (Ch. 20). What is electrostatics?. The study of STATIC ELECTRICITY.. Static electricity is electrical charges that can be collected and/or held in one place.. This is different from . current electricity. Electric Force. Whiteboard Particle Model . (remember sticky tape lab?). H. ow . you can . make a balloon stick on the wall?. What is occurring on the atomic level that lets you do this?. The atom. The atom has positive charge in the nucleus, located in the protons. . 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.
