What else can I help you with?
There is no gravity air and what on the moon?
The Moon does have gravity! It is weak (just 1/6th of the Earth's) so the Moon has very little atmosphere.
Why their is no air in space?
The atmosphere we breath is held round the earth's surface due to earth's gravity. Without this gravity, earth's atmosphere would disperse into space. Because our moon's gravity is weak, so there is no atmosphere on the moon.
Is the Moon's gravity stronger than a pencil?
Yes, the Moon's gravity is much stronger than that of a pencil. The Moon's gravity is what causes tides on Earth and keeps it in orbit around the Earth, while a pencil's gravity is too weak to have any noticeable effect.
Is the gravity on earth strong or weak?
Compared to the moon, it's pretty strong. Compared to Jupiter, it's pretty weak.
How is it that the Moon's gravity is strong enough to effect earth's tides yet weak enough for man to bounce around?
The moon's gravity is constant. The variable in the question is the object's size. The moon impacts our tides, and other liquids, because it rotates around the earth and 'pulls' the water on earth's surface. The astronauts who walked on the moon experienced gravity proportionate to the size of the moon, which is smaller than the earth. Therefore, gravity exerted less force, allowing them to bounce.
Why does the moon have gravity but no air?
The moon has gravity because it has mass, which creates a gravitational pull. However, the moon has no atmosphere because its gravity is too weak to hold on to gases like air. As a result, the moon has a vacuum environment with no air or atmosphere.
Why does the moon have no gravity?
It does. Who told you it doesn't? All objects that have mass have gravity. The more mass they have, the more gravity they have. For small objects, the gravity is so weak as to be almost indetectable, even with extremely sensitive instruments. However, the moon's gravity is certainly strong enough to be not merely detectable but to actually physically feel. The moon's mass is about 1/80th that of Earth, but its radius is also quite a bit less; the combination of the two yields a lunar surface gravity of about 1/6 that of Earth.
What is one effect of the weak gravity on the moon?
A person from Earth jumping on the Moon will jump almost 5 times higher than they can on earth. If you weighed yourself as 100 pounds on Earth, you would only weight about 17 pounds on the Moon.
Why is the weight of an object on earth different from its weight on the moon?
Because earth is a larger planet than the moon, it has a stronger gravity. Bigger the planet > Stronger the gravity. That is the rule. Since our moon is a much smaller planet, it has weak gravity, and so the object is not being pulled down as hard, so it reduces the overall mass.
What does gravity have to do with the moon and the sun?
Gravity has to do with everything in the universe. Gravity pulls the Moon toward the Earth, but its orbital speed prevents it from falling into it (it falls"around" the Earth in a slightly elliptical orbit). Similarly, the Sun's gravity keeps the Earth and Moon, and the other planets, in their orbits.
Why lack of atmosphere around the moon?
The moon's gravity is too weak to hold on to an atmosphere.
Does earth have strong or weak gravity?
Because of Earth's size, and considering it as one of the smallest planets, it has a weak gravity compared to the OTHER planets. Most planets have greater gravity because of their size. Earth has a stronger gravity compared to mars, mercury, and venus.
