Overall the Moon is less dense in comparison to the Earth as a whole.The Moon is second only to Lo where density of different moons in the Solar System is concerned. Lo with a density of 353kg/m 3 is the densest moon to be discovered so far in the Solar System.his means that the Earth is denser than the Moon. Weight is the effect of gravity on a Mass and is less on moon and therefore less gravity than earth and Density is mass/volume and since mass is constant, density would also be constant.
The low density of the Moon means that it has less mass, and less gravity. If you ever get a chance to stand on the Moon, you’ll see that its gravity is only 16.5% the gravity of Earth. In other words, if you weight 100 kg on Earth, you would only weigh 16.5 kg on the Moon. The density of Io is 3.53 g/cm 3. Astronomers believe that the Moon formed when a Mars-sized object crashed into the Earth. The resulting debris from the collision collected into orbit around the Earth and became the Moon. Report Abuse. There is about 1/6 the gravity on the moon as there is on Earth. Density of a liquid with a constant volume, varies according to the weight. The higher the weight, the higher the density. Report Abuse. In physics, density is defined as mass per unit volume, not as weight per unit volume. A kilogram is a unit of mass, not weight. Moving an object into a different gravity field changes its weight, but not its mass. Therefore, the density of water is the same on Earth or on the moon. In high school, density is defined as stupidity; slow-wittedness; obtuseness, not as the ability to sink and drown in a wading pool The density of Earth is 5.52 g/cm 3. This makes it the densest planet in the Solar System. The density of Io is 3.53 g/cm 3. Astronomers believe that the Moon formed when a Mars-sized object crashed into the Earth. The resulting debris from the collision collected into orbit around the Earth and became the Moon. Effective gravity on the Earth's surface varies by around 0.7%, from 9.7639 m/s 2 on the Nevado Huascaran huascarán mountain In peru to.9 8337/m s 2 at the surface of The Arctic. Ocean in large, cities it ranges from.9 766 In Kuala, Lumpur Mexico, city And singapore to.9 825 In oslo And. helsinki Gravity decreases with altitude as one rises above the Earth's surface because greater altitude means greater distance from the Earth's centre. All other things being equal, an increase in altitude from sea level to 9,000 metres (30,000 ft) causes a weight decrease of about 0.29%. Weight density is not a term. Weight is the effect of gravity on a Mass and will be less on the Moon since the moon has less mass and therefore less gravity than the Earth. De … nsity is mass/volume and since mass is constant, density would also be constant. 2 people found this useful. Your weight would change since the moon has a different gravitational acceleration than earth. We = (m) (ge) Wm = (m) (gm) _________________________________________________________________________________________________ The mass is the samethe Moon has about 1/6th the gravity on earth. Hence the density of Moon is measured as the mass of the satellite per unit volume. Density of Moon and Earth: The Moon’s density is a low 3346.4 kg/m 3 or 3.3464 g/cm 3. The Earths density is 5515kg/ m 3 or 5.515g/ cm 3. This means that the Earth is denser than the Moon. Comparison of Moon’s density with Earth and Lo. The average density of the Moon is approximately similar to the density of the Earth mantle. However, overall the Moon is less dense in comparison to the Earth as a whole. The Moon is second only to Lo where density of different moons in the Solar System is concerned. Lo with a density of 353kg/m 3 is the densest moon to be discovered so far in the Solar System But Earth's Moon with a density of 3.3 g/cm 3 is very different from the Earth and from the other bodies in the inner solar system. This was one of the first clues that the origin of the Moon was not just accretion from the same material from which the Earth was formed.
