Because the moon has much less mass than the earth, so its gravitational attraction at the surface is only about 1/6 that at the surface of the earth.

Because of its smaller size and mass, the gravity of the Moon is about 1/6 the gravity on the Earth. That means that a person who weighs 180 pounds on Earth would only weigh 30 pounds, if measured on the Moon. That is why when the astronauts were on the Moon, they were able to jump so high--even while wearing the heavy space suit

It has to do both with mass and radius. A large body with lots of mass can have the same gravity as us...for example, the planet Saturn has much greater mass than the earth but, because of it's large radius, the gravity at cloudtops on it (the surface we see) is just barely more than the earth. The mass of the moon is just 1/81 that of the earth, but it's small radius means the gravity on it is 1/6th that of earth. Hence, astronauts weigh less there than here.

The bigger the object the bigger the gravity. Everything has gravity a paper a book and yourself you'de have to be like a billion times bigger to atract anything to yourself. The moon is 1/6 of the earth so less gravity which means less weight is being forced on youself on the moon.

Because the moon has less mass than the Earth. The force of gravity is dependent on the masses of the two objects in question and the inverse square of the distance between them.

because the gravitational pull on the moon is 1/6 that of the earth

b) the gravitational field power is far less on the moon's floor than on earth's floor the moon is a few million/6th the dimensions of the earth so it has some million/6 of the gravity

the gravitational pull on the moon is just 1/6 of the earth, so basicallly it has very less gravity

they weigh lesser on the moon because of the lesser gravitational pull present on the surface of the moon. that is also the reason why they float!

Not only on the moon, in space. Because in space, there isn't any gravity. I guess that's the reason why. I Go www.google.com and check it out.
