The formula for potential energy is PE = m g•h. In this formula, PE stands for potential energy (in joules), m stands for mass (in kilograms), h stands for height (in meters), and g stands for acceleration caused by gravity. On Earth's surface, g is 9.8 m/s?. This means that every second, the speed of a falling object increases by 9.8 m/s. Calculate the potential energy of a 20 kg sled at 40 meters. Show your work. When you are done, use the Gizmo to check your answer.
