stored energy, such as the stored energy of a sled at the top of a hill. question: how are potential and kinetic energy related to one another? collect data: turn on show energy. notice that energy is measured in joules (j). in the table, record the potential and kinetic energy of the sled at the top of the slope, about halfway down, and at the bottom. (use the pause button to stop the sled halfway down.) location height potential energy kinetic energy total energy top 25.0 m middle bottom 0.0 m how do the potential and kinetic energy change as the sled moves down the slope? add the potential and kinetic energy for each location to find the total energy. what do you notice about the total energy? according to the law of conservation of energy, energy can be changed from one form to another, but it cannot be created or destroyed. that means that the total amount of energy at the beginning is the same as the total amount at the end.
