Rotational Kinetic energy of a Hypothetical Planet?

Click For Summary
SUMMARY

The discussion centers on the feasibility of extracting rotational kinetic energy from a hypothetical Earth-like planet with Jupiter's size and a 24-hour rotation period. Participants emphasize the physical impossibility of an Earth-like composition achieving Jupiter's size, suggesting that such a planet would not exist under known physical laws. The conversation highlights the need for accurate calculations and understanding of planetary physics to estimate rotational energy, which is critical for any scientific or fictional exploration of such a concept.

PREREQUISITES
  • Understanding of rotational kinetic energy concepts
  • Familiarity with planetary physics and composition
  • Basic knowledge of the laws of motion and gravitation
  • Ability to perform calculations involving mass and rotational speed
NEXT STEPS
  • Research the formula for calculating rotational kinetic energy
  • Study the physical properties of gas giants versus terrestrial planets
  • Explore the implications of planetary size on composition and stability
  • Learn about the physics of planetary rotation and its effects on energy extraction
USEFUL FOR

Physics students, science fiction writers, and anyone interested in planetary science and energy extraction concepts.

Would there be any way to get the energy from the rotation of a planet, which is an Earth like planet in material, sized like Jupiter, and seems to have a 24 hr day.

I am just starting to get into real Physics, So I am not even sure where to start getting the numbers to work with, and I would like a more accurate answer then one I would get on my own. So if someone could tell me even an estimate of what it would be, that would help.

I certainly don't want to deter you from your project, since I sometimes write science fiction myself (I assume that you are doing so, based upon the question), and I'm really glad to see that you are seeking true information rather than making up something absurd. I'm not going to try to address your main question until one thing gets clarified. I don't think that it's in any way possible to have a planet of Earth-like composition achieve anything like the size of Jupiter. Jupiter is a star that didn't quite make it through puberty. Is there some reason that you need it to be so?
