Earth's unimpeded rotation for billions of years [duplicate]
My nephew (7th grade) has stumped me with this question.
If I spin a top, it eventually stops, because of friction, air
resistance etc. How come the Earth has been spinning non-stop for 4.5
Billion ...

Angular momentum of the earth
We know the tidal waves are decreasing the spin rate of the earth which causes the days to longer, so as the angular momentum of the earth decreases it means it rotational kinetic energy also ...

Variance of earth's rotational speed due to tidal effects
I recently watched a video that explained how the length of the day was impacted by where the Earth was at in its orbit around the Sun. Consider a "day" for a point on Earth the period from when the ...

Fact: The Earth is rotating on it's own axis every 24 hours.
Question: If, for some reason I won't specify the current speed of the Earth and could slow it down(say by 5%). Will it speed up again ...

Angular momentum power plant on Earth
If tidal power plants are slowing down Earth's rotation then is it theoretically possible to build a power plant that would drain energy from Earth's angular momentum (thus slowing down it's rotation)?...

How long was a day at the creation of Earth?
Since the earth is slowing its rotation, and as far as I know, each day is 1 second longer every about 1.5 years, how long was an earth day near the formation of earth (4.5 billion years ago)?
I ...
