Lamar writes several equations trying to better understand potential energy. h = d with an arrow to the equation w = f d and p e subscript g baseline = m g h. f subscript g baseline = mg with arrows to the f in w = f d and to p e subscript g baseline = m g h. what conclusion is best supported by lamar's work? the elastic potential energy is the same for any distance from a reference point. the gravitational potential energy equals the work needed to lift the object. the gravitational potential energy is the same for any distance from a reference point. the elastic potential energy equals the work needed to stretch the object.
