Which of the following statement (s) is/are correct regarding gravitational potential energy, Vg? The position of the center of gravity of the body, yG, is measured with respect to the datum plane/line. Select all that apply. Group of answer choices The work done by the weight is negative if the weight moves the object up with respect to the datum as the direction of the weight and y are opposite. The gravitational potential energy is positive when yG is positive upward with respect to the datum as the weight has the ability to do positive work when the body moves back to the datum. The gravitational potential energy is negative if the body's G is located below the datum since the weight does negative work when the body returns to the datum. The potential gravitational energy of the body is always positive regardless of the position of G with respect to the datum
