PHYS 211 Lecture 16Outline of Last Lecture I. WorkOutline of Current Lecture I. Work done by a variable forceII. The Work – Energy TheoremCurrent LectureI. Work done by a variable forceExample: the force exerted by a spring varies linearly with the displacementk = spring constant, x = distanceII. The Work-Energy TheoremThis relationship is called the work-energy theoremThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.Equations we can use as a result of the work-energy theorem: A .25 kg puck is acted upon by a stick with a force of 6N for .5m. What is its kinetic energy? How much work is needed to stop it?GPEi + KEi + W = GPEf + KefW = Fd = (6N)(.5m) =
