Name: PHYSICS 1112 Chapter 19- Warm-Up due August 30th Reading Objectives: In PHYS1111 you learned about potential energy (PE = mg h). In section 19.1 you will learn about electric potential energy. Can you find any similitudes? Another important concept you will learn in section 19.1 is electric potential. Wow, these two terms sound pretty similar, but they and electric potential? Equations 19.2 and 19.7 relate these two concepts. are not. What are the units of the potential energy What is an electron-volt? Conservation of energy. Be sure to work out example 19.3 Warm-up 1. Calculate the gravitational potential energy and kinetic energy for each position marked in the figure below. You should have done this in your PHYS1111 class.
