Michael Fowler UVa Todays Topics Field lines and equipotentials Partial derivatives Potential along a line from two charges Electric breakdown of air Potential Energies Just Add Suppose you want to bring one charge . We offer the widest selection of horse fencing, electric fences, polytapes, energizers, polyrope, fencing accessories and other equine products. Objective: TSW understand, transfer and apply energy concepts to electric fields and charges by solving problems involving electric fields and forces.. Let’s revisit energy concepts for a gravitational field. A 250 gram baseball is thrown upward with an initial velocity of 25m/s. What is the maximum height reached by the ball?. Physics 2102. Gabriela Gonz. á. lez. Physics 2102 . Electric Potential on Perpendicular Bisector of Dipole. You bring a charge of -3C from infinity to a point P on the perpendicular bisector of a dipole as shown.. Physics 2415 Lecture 6. Michael Fowler, UVa. Today’s Topics. Some reminders about gravity: . mgh. and its electric cousin. Inverse square law and its potential. Field lines and . equipotentials. . Electric Potential (Energy). Charges. The fundamental rule at the base of all electrical phenomena is that . like charges repel and opposite charges attract. An object that has unequal numbers of electrons and protons is . Michael Fowler, . UVa. Today’s Topics. A bit more about mirrors…. Refraction. Lenses. Ray tracing to locate image. Concave Mirror Focusing Sunlight. This solar collector is really many small flat mirrors, but equivalent to a concave mirror focusing parallel rays to a point half way from the center of the mirror to its center of curvature.. Michael Fowler, . UVa. Today’s Topics. Huygens’ principle and refraction. Snell’s law and applications. Dispersion. Total internal reflection. Huygens’ Principle. Newton’s contemporary Christian Huygens believed light to be a wave, and pictured its propagation as follows: at any instant, the wave front has reached a certain line or curve. From every point on this wave front, a . Lecture 1. Michael Fowler. Basic Outline. The course has three main parts, each about a month: . Electrostatics.. Magnetism and Magnetic Induction..
