Historical Perspective: The Genius of Isaac NewtonĪ beautifully-organized glimpse into Isaac Newton’s work through three strands: mathematics, physics, and philosophy. The Physics Classroom Tutorial, Newton's Laws of Motion Chapter, Lesson 2.The Physics Classroom Tutorial, Newton's Laws of Motion Chapter, Lesson 1.Readings from The Physics Classroom Tutorial To analyze representations of physical situations (dot diagrams, motion graphs, force diagrams) and to predict whether or not the forces are balanced or unbalanced. To refute the misconceptions that (a) forces are required to sustain the motion of an object, (b) an object moving in a given direction must be experiencing a force in that direction, and (c) that contact forces persist even after the contact ceases. To understand that force is an interaction between objects and to be able to recognize the presence and absence of specific force types. To define inertia and to identify the variables that affect and do not affect the amount of inertia an object possesses. To state Newton's first law of motion and to describe several examples of the law in operation. Teacher Toolkits » Newton's First Law » Newton's First Law - Complete Toolkit
