SUMMARY

The discussion centers on the implications of an increased rotational speed of the Earth, specifically the potential consequences before the planet breaks apart. Key points include the prediction of shortened days, altered sleep patterns, intensified weather events, and changes in ocean depths and tides. The maximum rotational velocity is determined by the centripetal acceleration equating to gravitational acceleration (g), necessitating complex calculations involving the Earth's material composition and dynamics. The conversation highlights the need for a thorough understanding of physics and planetary dynamics to explore these scenarios.

PREREQUISITES
  • Understanding of centripetal acceleration and gravitational forces
  • Knowledge of planetary dynamics and material composition
  • Familiarity with fluid dynamics principles
  • Basic grasp of rotational motion physics
NEXT STEPS
  • Research the equation for centripetal acceleration and its implications on planetary rotation
  • Explore the effects of increased rotational speed on weather patterns and ocean dynamics
  • Study the material properties of Earth's layers and their response to stress
  • Investigate historical data on Earth's rotation and its geological impacts
USEFUL FOR

Students of physics, geophysicists, climate scientists, and anyone interested in the dynamics of planetary motion and its effects on Earth’s environment.

I've noticed there are a lot of documentaries and youtube videos about what would happen if the Earth stopped spinning.

However, I would like to know what would happen if the Earth kept speeding up, what would happen if it did, and the approximate maximum rotational velocity before the Earth broke apart or something. I imagine it would be fairly difficult to calculate the speed because it entirely depends on the material composition of the Earth's layers and a massive dynamics calculation as well as fluid analysis, etc. Thanks for your help in advance.
 
Physics news on Phys.org
Did you search on your question? I found several articles that talk about what might happen.

Before the Earth breaks apart, there would be a host of lesser catastrophes like shortened days, shortened sleep periods, more violent weather, changing ocean depths and tides...

Is this a homework question?
 
Note that a planet doesn't take to tension forces very well, so the limit (not considering a host of other factors like deformation) would be a rotation rate that results in a centripetal acceleration equal to g. You can Google for the equation.
