All the forces acting downward. P. otential energy. T. otal mechanical energy. Energy conservation. Lecture 11: Potential energy. Conservative forces. A force is called . conservative. if the work it does on an object as the object goes between two points is . Objectives: . Define mechanical work.. Calculate the work done in various situations.. . Work = . Fcos. d. Defining work. The Three Requirements. for Work: . Force, displacement, and cause. the force of friction points parallel and up the ramp.. the force of friction points parallel and down the ramp.. there is no friction force since the motion is at a constant speed.. None of the above.. Lesson 14. February . 10. th. , 2011. DEMO TIME. Can you drop the penny in the flask by only touching the ring? . Question:.
