An illustration with a slide. The top of the slide is labeled A, the middle is labeled b and the bottom of the slide is labeled C. Each sentence describes potential and kinetic energy at various locations on a slide. Complete each statement by selecting the position of the object on the slide. An object at position has all kinetic energy. An object at position has all potential energy. An object at position has about half potential energy and half kinetic energy.
