SUMMARY

The Earth derives its rotational energy from the initial conditions of its formation and does not require continuous energy input to maintain its rotation. According to Newton's first law of motion and the principle of conservation of energy, once the Earth begins to rotate, it will continue to do so indefinitely unless acted upon by an external force. This principle explains why planets, including Earth, maintain their rotation without needing additional energy from external sources such as the Sun.

PREREQUISITES
  • Understanding of Newton's first law of motion
  • Familiarity with the principle of conservation of energy
  • Basic knowledge of planetary formation
  • Concept of rotational motion in physics
NEXT STEPS
  • Research the implications of Newton's first law of motion on celestial bodies
  • Explore the concept of conservation of angular momentum in astrophysics
  • Study the processes involved in planetary formation and their effects on rotation
  • Investigate the forces that can alter a planet's rotation, such as tidal forces
USEFUL FOR

Students of physics, educators in astronomy, and anyone interested in understanding the fundamental principles governing planetary motion and energy conservation.

from where does Earth get energy for rotation?as its rotating means its doing some motion to work again sun's gravity soo from where does Earth gets this energy?
 
Physics news on Phys.org
No, the Earth is not doing work against the sun, so no input is required.
 
but anyhow how Earth gets energy for rotation?
 
Like I said, no energy input is required. That is due to Newton's first law and conservation of energy.
 
google... "why do planets rotate"

And once they "start" they don't need energy, as Russ explained.
 
Once something is rotating, it doesn't need energy to keep on rotating. In fact, it needs energy to STOP it from rotating.
