Physics 4B Lecture Notes 22-1 Introduction Go over the roll and introductory handout. Review of Physics 4A Newton's Laws of Motion explain the concept of force. 1. Newton's First Law - The Law of Inertia describes the natural state of motion as constant velocity defines force as the thing that causes changes from this natural state 2. Newton's Second Law - F=ma defines mass as the inertia of an object quantifies the amount of force required to make a given change in motion 3. Newton's Third Law - The Law of Action/Reaction forces always occur in action/reaction pairs Conservation Laws 1. Conservation of Energy 2. Conservation of Linear Momentum 3. Conservation of Angular Momentum Study of the Gravitational Force 1. The Law of Universal Gravitation F g = G m 1 m 2 r 2 Preview of the Rest of Physics The Four Fundamental Forces The most common force in every day life is the electric force. All contact forces (friction, normal, tension, pushes pulls, etc.) are actually electrical in nature. These electric forces are the topic for the next 15 weeks. Chapter 22 - Electric Charge Problem Set #1 - due: Ch 22 - 3, 5, 8, 10, 12, 20, 28, 29 The fundamental electric interaction is the force exerted and felt by electric charges. Lecture Outline 1. The Properties of Electric Charge 2. The Electric Force and Coulomb's Rule 1. The Properties of Electric Charge Pith Balls, plastic rod, fur Notice: 1) This force is stronger than gravity.
