PHYSICS 1112 Chapter 21-WarmUp due 23 January. Reading Objectives Name: . There are many types of potential energy including the usual gravitational (think mgy) and elastic (think KX"72), You wall be introduced to electric potential energy (in Joules) and how it's related to electric tential (in Volts) on the bottom of page 667. This section can be tough sledding so be patient. We'll up the mess and get in some comfort zone in class. We'll be particularly interested in distinguishing...

3. For experiment A, use equations 1&3 to develop a general equation for the value of tension (T) based on the values of the two masses. You will need this later to answer lab question (4), so write it in now. 4. Based on the "net force" and "total mass" approach that was used to derive equations 3,4, and 5; develop the equation for acceleration of two masses (m, and m2) hanging vertically from either side of a frictionless pulley....
