Explain why the force of gravity is weaker on the Moon than it is on the Earth?
The force of gravity is weaker on the Moon than on Earth because the Moon has less mass and a smaller radius than Earth. The gravitational force between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them, so the smaller mass and radius of the Moon result in a weaker gravitational pull.
How does mercury's size compare to the size of earth?
That depends what you mean by "size". Diameter: 0.38 times the diameter of Earth. Radius: same number, since the radius is half the diameter. Volume: the ratio of the diameters cubed. Mass: 0.055 times Earth's mass.
What is the mass of the planet with the largest radius?
In our solar system, Jupiter is the planet with the largest radius of 71,492 km It has a mass of 1.8986×1027 kg
Why gravity on earth is greater than that of moon?
Because the Earth has 80 times as much mass as the Moon has, and the greater radius of the Earth is not enough to cancel the effect of the mass difference.
Why does an object have a different weight on the moon than it does on Earth?
"Weight" is the force of gravity between two masses. Its strength depends on the mass of both masses and the distance between their centers. In the case of your weight, the two masses are you and the planet you're standing on, and the distance is the distance between the center of you and the center of the planet you're standing on. The moon's mass is different from the Earth's mass (by about 80 times), and its radius is different from the Earth's radius (by about 3 times). That's why the force that depends on both of these quantities comes out different on the Earth and moon.
How does Venus compare with the earth radius and mass?
Venus' radius = 0.95 of Earth's Venus' mass = 0.815 of Earth's
What is the Moon's mass and radius compaed with earth?
Mass: Earth's is 81.7 times the moon's mass.Radius: Earth's is 3.67 times the moon's radius.
What is the relation between the revolution of the earth around sun and the earth's mass?
There is no relation, any object with the same same distance as the Earth from the sun would complete one orbit in one year.

The gravitational force between two objects is directly proportional to their masses and inversely proportional to the square of the distance between them, so the smaller mass and radius of the Moon result in a weaker gravitational pull.
How do mercury radius and mass compare with the earths?
Mercurys mean radius is around 2,439.7 km, which is around 38.39% of earth radius or 0.3829 Earths. Mercurys mass is around 3.3022×10 to the 23 kg, around 5.5% of earths mass or 0.055 Earths.
How do they measure the earths mass?
-- Take an object of known mass, such as a liter of water.-- Measure the force of gravitational attraction between it and the earth, by placing it on a scale and "weighing" it.-- Knowing the distance from the center of the earth (earth's "radius") and the value of the Gravitational constant,and using the formula for the gravitational force between two masses, the earth's mass can now be calculated.
What is the relation between the mass and period of the pendulum?
The period is independent of the mass.
How is big is Saturn compared to Earth?
Saturn's radius is 9.4 x Earth's radius (equatoral) Saturn's mass is 95.2 x Earth's mass Saturn is 9.5 times further from the Sun than the earth is

The relationship between inertial mass and grvitational mass?
inertial mass (m) = 1Kg gravitational mass = GmM/R2 where G = 6.673x10-11m3kg-1s-2 m = inertial mass 1Kg M = mass of the Earth R= Radius of the Earth gravitational mass = 9.8 Newtons depending on your latitude.
What is the mass of the planet with the largest radius?
In our solar system, Jupiter is the planet with the largest radius of 71,492 km It has a mass of 1.8986×1027 kg
How big is the earth compeard to the moon?
The Moon's radius is slightly over a quarter that of Earth's, but its mass is only about 1/80 as much as the Earth's mass.
