Potential Discovery or Invention
Assuming that the Earth is a 0-mass hollow sphere, how much is the centrifugal force at the ground level due to its rotation at 1 revolution per 24 hours?
Is the centrifugal force negligible, or is it taken into account in the calculations of Earth's mass and gravity as well as in interactions between the Earth and the Moon, etc.? My 20-year old physics textbook does not mention the centrifugal force of the Earth in deriving "g = 9.8 metre/second^2"...
