Explain why your weight would be less on the Moon than on Earth, even though your mass would not change. Use the law of universal gravitation in your explanation.

Asked by kaitlynrae

Answer (3)

your weight would be less because gravity causes it to do so. your mass would not change because you are still made up of the same amount of mass.
PS. I couldn't use the law of universal gravitation sorry!

Your weight would be less on the Moon than on Earth because weight depends on the gravity at a location. While your mass remains the same regardless of where you are, the Moon's gravity is only about one-sixth of Earth's gravity. According to Newton's law of universal gravitation, the force you feel due to gravity is dependent on the mass of the two objects (in this case, you and the Moon) and the distance between their centers, but it also depends on a constant.
Since the Moon's mass and radius are both less than Earth's, the resulting gravitational acceleration is weaker, resulting in a lower weight. Therefore, even though your mass is constant, the reduced gravity on the Moon means you would 'weigh' much less.

You would weigh less on the Moon than on Earth because the Moon has a lower gravitational force. While your mass stays constant, the weaker gravity results in a lower weight on the Moon. Specifically, the gravitational acceleration on the Moon is about one-sixth of that on Earth, making you feel lighter there.
