Gravitational Potential Energy Gravitational potential energy of an object is (Potential Energy) = (Weight) x (Height) PE = m•g•h = mgh where m is mass of object in kg, h is height of object in m, and g = 9.8 N/kg = 9.8 m/s2 Choose h = 0 to be at a convenient place 9-Sep-10 Physics 101 Reference Level for PE grav A location where the ... ................
