Explain how to calculate the position of the common centre of mass of the Earth-Moon system?
The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon. (For more than 2 objects, the calculation is somewhat more complicated - reading about "center of mass" can give you an idea.)The distance from the center of mass to Earth, times the mass of the Earth, must be equal to the distance of the center of mass to the Moon, times the mass of the Moon.

Is the mass of the moon greater than the mass of the earth?
No. The mass of the moon is a fraction of the earth's mass.
Does the earth and the moon have the same amount of mass?
No, they do not have the same mass. The moon has much less mass than Earth.
What is the mass of the Moon compared to the mass of the Earth in fractions?
The mass of the moon is about 1/80 that of Earth.
Why are you NOT weightless on the moon?
Because the Moon has mass, a LOT of mass. If something has mass, it will have gravitational attraction. The more mass, the greater the attraction. The moon has ~1/6th the gravity as the Earth.

Does the moon give gravity to the earth?
No. Earth's gravity is due to Earth's own mass. The moon has its own gravity due to its mass, but that gravity is much weaker than Earth's.
Is the mass of the moon greater than the mass of the earth?
No. The mass of the moon is a fraction of the earth's mass.
What is the mass of Moon's?
The mass of the Moon is 7.3477 × 1022 kg.AdditionallyIn comparison to Earth, mass of moon = 0.0123 Earths. The Moon's mass is 1/81 of Earth's.
What is the moon's mass compared to the earth's mass?
1 earth mass = 81.78 moon mass (rounded)1 moon mass = 0.01223 earth mass = 1.223% of earth mass (rounded)The mass of the moon is only 1.2 percent of the mass of Earth.
Does the earth and the moon have the same amount of mass?
No, they do not have the same mass. The moon has much less mass than Earth.
What are the 3 factors of weight?
The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.The mass of the object, the mass of the object that is attracting it and the distance between their centres of gravity.So your weight on the moon will depend on your mass, the moon's mass and the distance from your centre of gravity to the moon's.
Is the moon more massive than the earth?
No. The earth's mass is equal to about 82 times the moon's mass. (Moon's mass is equal to about 1.2% of the earth's mass.)
What percentage of moon mass is earths mass?
Earth's moon is roughly 1.2% the mass of earth.
What is the mass of the Moon compared to the mass of the Earth in fractions?
The mass of the moon is about 1/80 that of Earth.
Which weighs more the moon or Pluto?
In terms of mass - not weight - the Moon has more mass than Pluto.The Moon has a mass of 7.3477 x 1022 kgPluto has a mass of 1.305 × 1022 kg or about 0.178 that of the Moon
Why are you NOT weightless on the moon?
Because the Moon has mass, a LOT of mass. If something has mass, it will have gravitational attraction. The more mass, the greater the attraction. The moon has ~1/6th the gravity as the Earth.
