Table of Contents Date Introduction to Electrostatics Page # Objective: SWBAT identify the type of electrostatic force that will apply to charged particles. Do Now: Brainstorm – What do you think is electrostatics? What do you know about Electrostatics?

Breaking Up the name Electro: Statics:

Definition Electrostatics: involves electric charges at rest, the forces between them and how they interact with the world.

What are electric charges? Most particles (such as electrons and protons) carry charge. Electric Charge: is a property of matter that can be positive or negative. Proton Electron

What are electrical forces? Review: What is a force? Electrical force: the force between two charged objects (particles) that can either attract or repel them.

Electric forces When two particles (objects) are brought close together they experience one of these electric forces: 1. Repel 2. Attract

When do particles repel? Repel: when the electrical force causes particles (objects) to accelerate away from each other. Particles (objects) repel when they are of the same charge. 1. Two positive charges 2. Two negative charges

Example problem What type of force will two protons (each holding a positive charge) experience when they are brought together? Describe the type of behavior you would you see? (show with arrows)

Example problem What type of force will two electrons (each holding a negative charge) experience when they are brought together? Describe the type of behavior you would you see? (show with arrows)

When do particles attract? Attract : when the electrical force causes particles (objects) to accelerate toward each other. Particles (objects) attract when they hold different charges. 1. One positive and one negative charge

Example problem What type of force will one electron (holding a negative charge) and one proton (holding a positive charge) experience when they are brought together? Describe the type of behavior you would you see? (show with arrows)
