The force of gravity is determined by the mass of two objects. Earth's is used as the standard. So on Earth your weight is the same as your mass.
Other planets have a different mass than the Earth, so the attraction - or gravity as we call it - differs as well.
The mass of the Moon creates a pull only 1/6 as strong as the Earth.
Mass can be more or densely packed together such as a gas or solid rock. The density of the material also affects the force of gravity at the surface. The force of gravity diminishes with distance. So, floating on a gas giant that has the same mass as the Earth, you would feel less gravity.
Yes, Earth has more gravity than the Moon. Earth's gravity is approximately 6 times stronger than the Moon's gravity.
-- The forces of gravity between two masses are inversely proportional tothe square of the distance between the masses, and directly proportionalto the product of the masses.-- The sun is about 390 times as far from us as the moon is.-- The square of 390 is 152,690.-- So each little pellet of mass in the moon attracts each little pellet of water onEarth 152,690 times as strongly as the same size pellet of solar mass does.-- The sun has 27.08 million times as much mass as the moon has. So all thepellets in the sun put together attract each little pellet of water on the Earth27.08 million times as strongly as the whole moon would if it were at the samedistance from us as the sun is.-- Put these two together, and you have 27.08 million times stronger, divided by152,690 times weaker, = 177.4 times as much force in favor of the sun.Surprise! The sun actually has a greater effect on the tides than the moon does.
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.

What would happen if you dropped a hammer and a feather on the earth and on the moon? The above experiment is supposed to prove the equivalence principle which states that the acceleration an object feels due to gravity does not depend on its mass, density, composition, colour or shape.Answer:If you drop a hammer and a feather from the same height on earth, the hammer will hit the ground first as the feather is slowed down drastically by air resistance.But on the moon, because it is a vacuum, and since the acceleration of an object is the same as the gravity i.e. a = g and the mass is not in the equation, all objects will have the same acceleration and hence the hammer should fall to the surface of moon at the same time as the feather but:"Both will hit the moon at the same time as believed by most scientists?"This may not be absolutely true since every object has its own gravity which is greater if its mass is greater. So the hammer has a gravity much greater than that of the feather. Therefore the combined gravity of the hammer and that of the moon (which pulls the hammer and moon towards each other) is greater than that of the feather and the moon.As such the hammer should collide with the moon marginally earlier than that between the feather and the moon, though this difference is so minute that we assume that the collisions occur simultaneously.However, if the hammer and feather are dropped together, then as the hammer's gravity pulls the moon towards itself, it also pull the moon towards the feather and as such the lucky feather may get a free ride and hits the moon at the same time as the hammer.To be fair, the experiment should be done dropping the objects individually e.g. feather first, then the hammer and then see whether the times taken are the same or not.All the above are valid only on the assumption that the centre of gravity is the part that hits the moon but since this is not necessarily true, we also have to take into account which part of the hammer or feather is nearest to the moon before the two objects were released (assuming that the centre of gravity of both objects are at the same level on release) !The real answer is that there is not enough data for us to know which will hit the moon first !The famous experiment by Astronaut Dave Scott on the moon is not very precise.Dr HW Looi
Earths surface of gravity is 4.6m/s2 more than moons.
Approximately 6 times more
The moon has about one-sixth the gravity of Earth.
Mainly because the sun is about 390 times farther away from Earth than the moon is. That means that there's about 153,000 times as much force between us and a piece of mass in the moon as there is between us and the same piece of mass in the sun.
the earths moon helps sustsian the gravity on the earths oceancs keeping them in balance
No, you will weigh 2 times less on the moon than on Earth. This is because the moon's gravity is 1/6th of Earths.
The moon's gravity is one-sixth that of the Earth's;
Moon gravity is less because the atmosphere and mass and the earths gravity is greater than the moon if you weight yourself in the earth and then you weighted yourself in the moon you would weight less in the moon you could actually float in the moon because of its atmosphere and mass
The moon does have gravity but it is much weaker it hase 1/6 of the earths gravity. wihout it how do you expect the men on the moon to stay on the moon?
The moon has one-sixth of the Earths gravity.
Earth's gravity is six times greater than the moon's.
Mainly because the Earth has about 80 times as much mass as the Moon has.
