How High Will It Go?
The motion of the sledder within the animation below is same to the motion of a roller coaster car on a roller coaster track. The similarity of the two motions is related along with the work-energy relationship. The energy bar charts accompanying the animation depict this relationship. Energy bar charts are a conceptual tool amount the amount of each form of energy possessed through an object as it is undergoes a particular motion. Observe from the animation in which the total mechanical energy TME of the sledder remains constant by the motion.
