The weight of an object depends on the gravitational force acting on it, which varies from planet to planet. The gravitational acceleration on the Moon is approximately 1/6th of that on Earth. Therefore, an object that weighs a certain amount on Earth (We) will weigh only 1/6th of that on the Moon (Wm). The correct relationship between the weights is given by the formula:
Wm = (1/6) × We
Which of the following quantities remains conserved when an object moves under the gravitational pull of another object?
