If the distance between the Earth and Moon were three times what it is now,by what factor would the force of gravity between them be changed.That is,what is the ratio of the new force to the old force?相关知识点: 试题来源: 解析 F=GMm/(r*r) R=3r So the ratio will be 1:9 ...

How did the moon form? How long does it take the moon to orbit Earth? How far is the moon from Earth? We tackle all of these questions (and more) in our guide.
.The journey to the moon had been the first step toward future exploration in space. The distance between the Moon and Earth is very short indeed when compared with the distances between Earth and the other planets. Mars, the nearest planet to Earth is m
The Moon is drifting away from us, with approximately 3.8 cm away from the Earth every year. The distance between the two planets is believed to have expanded from the original 20,000 kilometers to the current 380,000 kilometers. 月球上的脚印能保存几百年 ...
Once two Solar-type stars are separated by more than a few thousand astronomical units (AU, the distance between the Earth and the Sun), the internal acceleration of the system will be in the regime where gravitational anomalies appear in galaxies. Crucially, any anomaly found in wide binaries...
How do we measure the distance between the Earth and the Moon? Over time, scientists have found new techniques to measure the distance from the moon to Earth. Each one is more accurate than the next. Find out more below. 1. Lunar Laser Ranging Experiments ...
