PPT-Electric Potential

Physics 2415 Lecture 6 Michael Fowler UVa Todays Topics Some reminders about gravity mgh and its electric cousin Inverse square law and its potential Field lines and equipotentials. Ranchers, farmers, and other horse owners know how important a safe environment is to raising horses. While it is essential to keep horses within the boundaries of your property and safe from would-be predators, these valuable animals can easily be injured by fence railing that cracks or splinters. 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?. Comparing shocks from static electricity and electric currents is like comparing apples and oranges, they are similar but quite different at the same time.. Every year many people are injured and sometimes killed from electrocution as even small amounts of electric current can be lethal. . . HW2:Chapter 21, Pb.1, Pb.12, Pb.13, Pb.25, . Pb.31, .
