Quest for Gravity Theory: Earth's Rotation Impact?

Click For Summary
SUMMARY

The discussion centers on the relationship between Earth's rotation and gravity, concluding that Earth's rotation does not influence gravity as a fundamental force. Gravity is a result of mass, while rotation is an inertial phenomenon related to kinetic energy. The conversation highlights that the centrifugal motion from rotation can create an illusion of gravity, particularly in artificial gravity scenarios. Additionally, it mentions the "frame-dragging" effect, which is being confirmed by the Gravity Probe B experiment.

PREREQUISITES
  • Understanding of fundamental forces, specifically gravity.
  • Knowledge of inertial phenomena and kinetic energy.
  • Familiarity with artificial gravity concepts.
  • Awareness of frame-dragging and its implications in physics.
NEXT STEPS
  • Research the principles of general relativity and its implications on gravity.
  • Explore the concept of centrifugal force and its role in artificial gravity.
  • Study the findings of the Gravity Probe B experiment and its impact on gravitational theories.
  • Investigate the differences between rotating and non-rotating reference frames in physics.
USEFUL FOR

Physicists, students of gravitational theory, and anyone interested in the dynamics of Earth's rotation and its effects on gravity.

Does rotation of the earth, become a variable in the quest for the theory of gravity?
 
Physics news on Phys.org
or is there an invisible force that causes rotation to occur and gravity to exist on earth?

Rotation of the Earth has not to do with gravity, especially as we consider general gravity.

No invisible or magical force! Rotation occurs as an inertial phenomenon (kinetic energy), while gravity is a fundamental force that results from its mass.
 
yeah gravity is a by product of mass, the more massive the object, the more gravity. now if you are talking about rotation and the creation of artificial gravity, then that's just the centrifugal motion created by the spin pushes anything towards the edges thus creating an illusion of gravity
 
I'm not sure I understand the question, but the gravity of the rotating Earth is ever so slightly different than the gravity it would have if it were non-rotating. This "frame-dragging" effect is currently being confirmed by Gravity probe B.
