They don't have less mass. They weigh less. That's completely different.
The gravity is less on the Moon, because the Moon is smaller than earth; it has less mass, and therefore "sucks" less than the earth. Weight is gravity times mass, you have the same mass on Earth and on the Moon (and in space), but weigh less on the moon.
because the moon has less mass then earth
There is gravity on the moon. It is about on sixth what it is on Earth. This is because the moon has less mass than Earth does.
The moon has less mass than Earth. Gravity is proportional to mass, so there is less gravity on the moon.
No, they do not have the same mass. The moon has much less mass than Earth.
You weigh less on the moon compared to Earth because the moon has less mass and gravity. The gravitational pull on the moon is about 1/6th of that on Earth, so your weight appears to be lighter on the moon.
The Moon has much less mass than the Earth.
The gravitational force on the Moon is less than that on Earth because the Moon has less mass than Earth. Gravity is directly proportional to mass, so the smaller mass of the Moon results in a weaker gravitational force.
Yes, a person's mass remains the same on the moon as it is on Earth. However, because the gravitational pull on the moon is weaker than on Earth, a person's weight would be less on the moon compared to Earth.
Because earth contains more matter as compared to moon.
It is because the moon has less mass than the earth.
Gravity is the attraction between masses. And since the moon has less mass than earth, the gravity is weaker there. Over a distance gravity is weaker.
