Chapt. 8Potential Energy and Mechanical EnergyMultiple-Choice Problems008 qmult 00100 1 1 2 easy memory: potential energy definitionExtra keywords:physci1. Potential energy is:a) the energy of position: it exists for nonconservative forces.b) the energy of position: it exists for conservative forces.c) the energy of motion: its formula isPE= (1/2)mv2.d) the energy of position: its formula isPE= (1/2)mv2.e) heat energy.008 qmult 00110 2 1 3 moderate memory: paths and a conservative force2. The work done by a conservative force on an object while the object moves on a path betweentwo endpoints is:a)INDEPENDENTof the path and endpoints.b)DEPENDENTon the path.c)INDEPENDENTof the path between the endpoints.d)DEPENDENTon the path, butNOTon the endpoints.e) equal to the path length.008 qmult 00120 1 4 1 easy deducto-memory: general potential energy formula3. “Let’s playJeopardy! For $100, the answer is: ΔPE=−W.”a) What is the formula relatingPOTENTIALenergy change in a conservative force fieldto work done by the conservative force (i.e., what is the general potential energy formula),
