ASSESSSMENT TASK OVERVIEW & PURPOSE: The student will examine the path of a projectile and explain the motion using a quadratic function. Equation of Motion F = ma Equation of Motion τ = Iα Work W = F∆x Work W = τ∆ϕ Linear momentum P = mv Angular Momentum L = Iω Linear Motion ofthe Partsofa RotatingBody When a rigid body rotates around a fixed axis, each part of the body moves in a circle, or in a circular arc: r2 r2 ∆φ L2 = ∆φ×r2 r1 r1 ∆φ L1 = ∆φ× r1 ∆φ 1. edu This book has been judgedto meet theevaluationcriteria set. Actually work in reverse – assume the equation of motion (Dirac Equation, Maxwell’s equation, etc), and cook up a Lagrangian that will yield the desired equation of motion • Then, use Lagrangian to get symmetries, path integrals, expectation values, projections, whatever you want. 2-D Motion Problems: Projectile Motion – Their Solutions 1. detailed presentations of the subjects can be found in the Bibliography and are cited in the text. 5 Summary of the Aircraft Equations of Motion Linearized at Straight-Line, Horizontal, Wings-Level, Zero-Sideslip Steady Flight 389 12. We’ll now consider an interestingdynamics problem not covered in most introductory texts, a rolling ball on a rotating, possibly tilted, surface. We next introduce the energy associated with rotational motion and the rotational analog of mass, known as the moment of inertia. Using mathematics is only one way to obtain a solution. First, draw free body diagrams of A and B. An object that moves at a constant rate is said to be in uniform motion.
