It the earth was half its mass, then it might only be able to hold half the atmosphere. In this case, it may not be able to maintain many species of life as we know it.
Mass remains the same; weight will be one half that of the same mass on earth.
The moon is not half the size of the earth. the earth has a mass of 3.98 X 1024 kg, and the moon only has a mass of 7.34 X 1022 kg, which is only about 0.012300 Earth masses.
The mass on the moon and the earth is the same but the weight changes.
Size: The Moon has about 1/4 of the diameter of Earth. Mass: The Moon has about 1/81 of the mass of Earth.
The value of the gravitational field strength on a planet with half the mass and half the radius of Earth would be the same as Earth's gravitational field strength. This is because the gravitational field strength depends only on the mass of the planet and the distance from the center, not on the size or density of the planet.
Assuming the earth is a sphere, it corresponds to the rule that M is proportional to radius^3 - shrinking the radius by half, we see: (1/2)^3 = 1/8, the earth has shrunk to a mere eighth of it's mass.
Yes, but the weight of that mass will be different.
Earth and Venus are similer because of there size and mass
Mass
That is because Earth has more gravity. Weight = mass x gravity.
The strength of gravity of an object is proportional to its mass. The moon has much less mass than earth does.
