What else can I help you with?
What force causes the moon to stay in orbit around the earth?
Earth's gravitational pull. See attached link for more information.
The moon is to the earth, as the earth is to what?
The moon is to the earth, as the earth is to the sun.
What phase is it when you cant see the moon because its between the earth and sun?
The Moon's phase when it's between the Earth and the sun is called a New Moon. It's in this position where at times there is a Solar Eclipse of the Sun. Please refer to the link I have attached.
What is bigger the moon or the earth?
Earth, by far.
Does the moon orbit Earth or does the Earth orbit the moon?
The moon orbits Earth.
How many moon does our earth have?
Our Earth has only the one moon.
Does earth have have a moon?
YesYes. We call it the moon.
Why does the moon move in in orbit around the earth?
The moon is trapped in the gravitational pull of the earth. The earth and the moon are trapped in the gravitational pull of the sun. It is like whirling a small weight attached to a length of string round your head. The only thing stopping the weight to fly off (into space) is the string - which is the same force of gravitational pull we experience from our orbit round the sun.
Can the earth and moon be physically attached by a cord at their equators and would doing so be of any use?
It would be impossible. While the same face of the moon always orients toward earth, from the moon's surface you would observe earth spinning on its axis, close to 30 times per month. There can be no physical tethering of the two bodies. Also, the moon's distance from earth changes over the course of a month, so this would cause problems for a physical tether.
How are are the earth and moon different?
The moon has easily visible craters, but the ones on earth have mostly weathered away. The Earth has wind and the moon doesn't. Earth has atmosphere but the moon doesn't have one.
An object attached to a spring scale reads 10 N on the surface of Earth. If the acceleration due to gravity on the Moon is 16th that of Earth and what would its reading be on the surface of the Mo?
The weight of the object on Earth is 10 N, which is determined by the gravitational force acting on it. Since the acceleration due to gravity on the Moon is 1/16th that of Earth, we can calculate the weight on the Moon by dividing the Earth weight by 16. Thus, the reading on the spring scale on the Moon would be approximately 0.625 N (10 N / 16).
What is the arrangement of earth the moon and the sun of a lunar eclipse?
Sun, Earth, Moon. The moon is covered by the Earth's shadow.
