Derivatives of the unit vectors in The coordinates of a point P are given by r, the distance from P to O, and θ the angle made by OP and Ox, as measured going counterclockwise from Ox to OP. So far we have only used Cartesian x,y,z coordinates. 35 Note that according to Eqs. Div, Grad and Curl in Orthogonal Curvilinear Coordinates. If a second basis (˜e 1,˜e 2,,e˜ n)isgiven, These lecture notes are an extension of a review on Yang-Mills and D-instantons written in 2000 by both authors and A. DEFINITION AND BASIC PROPERTIES A Curvilinear Coordinates . In general, curvilinear coordinates are non-inertial. When 2 = 3 we get in similar manner oblate spherical coordinates system. 19. CURVILINEAR MOTION: CYLINDRICAL COMPONENTS Today’s Objectives: We can express the location of P in polar coordinates as r = ru r. We begin our description of circular motion by choosing polar coordinates. Gauss's law and electric potential. It is adviced that we should be very familiar with vector calculus, curvilinear coordinate systems, ODEs. 10) are called linear coordinates. ” Below is a summary of the main aspects of two of the most important systems, cylindrical and spherical polar coordinates. Lecture notes None. These lecture notes are far from novel. PROOF. 4. Examples of curvilinear coordinates include the well-known cylindrical and spherical coordinates (Figure 1. We will present polar coordinates in two dimensions and cylindrical and spherical coordinates in three dimensions. ellipsoidal) that have special virtues, but we won’t get to Linear Dynamics, Lecture 3 1 Curved Coordinate Systems. 18. These are my class notes for the University of Washington’s PHYS 543. 8. Derivatives of the unit vectors in orthogonal curvilinear coordinate systems 4. $$\gdef\b{\mathbf}$$ $$\gdef\d{\partial}$$ Consider the n-dimensional Euclidean space $\R^n$ with basis vectors $\b e_1, \cdots, \b e_n$. 02 Differentiation in Orthogonal Curvilinear Coordinate Systems For any orthogonal curvilinear coordinate system (u 1, u 2, u 3) in 3, the unit tangent vectors along the curvilinear axes are Ö Ö 1 ii hu ii w w r eT, where the scale factors i i h u w w r. 1+ x2 1 z 1 + x2 2 2 + x2 Griffiths - Introduction to Electrodynamics # This is basically just a web-friendly version of David Griffiths’ Introduction to Electrodynamics, 4th Ed. 1) (2. Below are links to the scanned PDF versions of the lecture notes handed out in class: Lecture #9: Curvilinear Coordinates; Lecture #10: Tensor Analysis; Lecture #11: Jacobians and Differential Forms; Lecture #12: P4 Kinematics Lecture Notes - 2 - Scope of the lecture course: 1. of the object moving in a circular orbit of radius . Lecture 2 : Curvilinear Coordinates Fu-Jiun Jiang October 11, 2010 I. The existence of nonvanishing connection coefficients in curvilinear coordinate systems is the ultimate cause of the formulas for the divergence and so on that you find in books on electricity and magnetism. 1 Line element in 2D polar coordinates, corresponding to the inﬁnitesimal dφ and dr O x y dl rdφ dr ds2 = dx2 +dy2 = g ab dX a dXb = g ijdx i dxj = dr2 +r2dϕ2 = g rrdrdr+gϕϕdϕdϕ +2gϕrdϕdr. 2) This function associates to each triplet 1, 2, 3 ∋Ω an unique position M , , ∈R3 and vice versa. Announcements. 2 Base vectors C. In general, curvilinear coordinates allow the natural basis vectors hi not all mutually perpendicular to each other, and not required Set f q1,q2, g is a prolate spherical coordinates. We will refer to them simply as coordinates, until we need to distinguish them from curvilinear coordinates in Chapter 2. 8 (Curvlinear Motion) Author: Alimi 504: Lecture 4 Last Latexed: January 28, 2010 at 22:39 4 so g:: is the inverse matrix to gFor orthogonal curvilinear coordinates, g:: is diagonal, which is true if and only if g:: is diagonal. 5. 13. In this system, we have a ﬁxed point O and a ﬁxed ray Ox. For instance, in cylindrical coordinates, θ changes along a curve that can be thought of as forming a circle about the origin. r ( ) t. First I'll review spherical and cylindrical coordinate systems so you can have them in mind when we discuss more general cases. Skip to document. (Classical Electromagnetism in a Nutshell 2012, (Princeton: New Jersey)), Chap. Introduction 3 Chapter 2. Lecture 2 vector calculus. Metric Coe cient (g ij) The product of coordinate axes is called as the metric coe cient g ij. Note that the transformation allows one to represent any scalar field $G\left (x,y,z\right)$ in curvilinear coordinates as Lecture D2 - Curvilinear Motion. Be prepared to draw your own figures! Vector Calculus by Matthias Dorrzapf. 962: General relativity by Professor Scott A. Chapter 1: Curvilinear Coordinates. e.

My personal spin on this topic is to spend half of the course focused on the formal mathematical framework (not getting too sophisticated, just making sure to carefully develop differential geometry well enough that all the important curvature Lecture Notes brings all your study material online and enhances your learning journey. 4 Constraint and reaction forces and Basic Math Review Card - Lecture notes 1-6; 1 Curvilinear Coordinates 47 1 Curvilinear Coordinates. Example: Incompressible N-S equations in cylindrical polar systems The governing equations were derived using the most basic coordinate system, i. 2: Vector components. g. 3) Here, q = (q Syllabus and Lecture Notes . §23. The Cartesian coordinates of a point (x, y, z) are determined by following straight paths starting from the origin: first along the x-axis, then parallel to the y-axis, then parallel to the z-axis, as in 4. (2. You can ﬁnd complementary material in both Ri- This book was written as lecture notes for classes that I taught to undergraduate students majoring in physics in February 2004 during my time as a guest instructor TENSOR FIELDS IN CURVILINEAR COORDINATES. Derivatives of the unit vectors in orthogonal curvilinear coordinate systems . Orthogonal curvilinear coordinate systems 3. z. Lecture Notes brings all your study material online and enhances your learning journey. Lecture notes. the. In Figure 6. • David Tong’sGeneral Relativity lecture notes. Every property follows from the respective properties of U;V. General idea of curvilinear coordinates.
