Therefore, the speed of Earth's rotation is about 1,038 mi/hr (1,670 km/hr) or roughly 1,000 mi/hr. FAQ How fast would the Earth have to spin to fling us off? The Earth's gravitational force is strong enough to keep objects on its surface even if it spins at a considerable sp...

Scientists have warned there could be a big increase in numbers of devastating earthquakes around the world next year. They believe variations in the speed of Earth’s rotation could trigger intense seismic activity, particularly in heavily populated tropical regions. 科学家警告称,明年,世界各地发生灾...
The concept of a day,defined by Earth's rotation(自转),has been the basis for timekeeping since ancient times.However,the speed of Earth's rotation is not always the same.It slows down due to the drag of tides,leading to the addition of"leap seconds"(闰秒) to atomic time(原子时间) to...

To solve the problem of calculating the angular speed of rotation of the Earth so that the apparent gravitational acceleration at the equator becomes half of its value at the surface, we can follow these steps:Step 1: Understand the rel
The rotation of the earth is a period of 86,164 seconds. The earth has a radius of 6,380 km. How fast would you be moving due to Earth's rotation at the equator? How fast would you be moving at a lati a) What is the angular speed omega about the polar axis of a point ...
may suggest that decrease of earth rotation speed probably has an important effect on the occurrence of an El Nino event. Its influence on the order of magnitudes of the weakening of equatorial ocean currentvelocityand the physical process of the formation of an El Nino event are also discussed...
