Document Summary
First step: develop a simplified representation of the motion so that key elements stand out. Second step: analyze the motion with the language of mathematics. Motion: the change of an object"s positon or orientation with time. Trajectory: the path along which an object moves, which might be a straight line or might be curved. Motion diagram: shows an object"s position at several spaced instants of time. You can keep track of an object"s motion with a single point. Particle: an object that can be represented as a mass as a single point. Treating an object as a particle is a simplification of reality. Model: allows us to focus on the important aspects of a phenomenon by excluding those aspects that play only a minor role. Particle model of motion: a simplification in which we treat a moving object as if all of its mass were concentrated at a single point.
