If a fast moving and heavy object strikes earth,can it change its spin or rotation or both?
OK then, we have given you the correct answers in posts #2 and #3. Enjoy.Thanks for reply.
By spin I meant about Earth axis and by rotation I meant rotation(revolution) of Earth about Sun.
For change in spin,I further specify that if the high speed heavy object pushes Earth almost tangentially(not just grazing)
Isn't all of China already East? They'd have to run west...If all of China started running east at the same time, that would do it.
The Earth takes approximately 24 hours, or one day, to complete one full rotation on its axis.
The Earth's rotation is caused by its initial spin during its formation and the conservation of angular momentum. Its rotation is also influenced by the gravitational pull of the Moon and the Sun.
Yes, the Earth's rotation causes it to bulge slightly at the equator and flatten at the poles, giving it an oblate spheroid shape.
Earth's rotation refers to its spinning on its axis, while its revolution refers to its orbit around the Sun. One rotation takes approximately 24 hours, while one revolution takes approximately 365.24 days.
Yes, the Earth's rotation is gradually slowing down due to tidal forces from the Moon and the Sun. This results in an increase in the length of a day by about 17 milliseconds every century.
