How will the value of `g` be effected if
(i) the rotatio of the Earth about its polar axis stops and
(ii) the rotational speed of the Earth about its polar axis is doubled?

The rotation of earth about its axis is

The rotation of earth about its axis is………..

If the speed of rotation of earth about its axis is increased,

On account of the earth rotating about its axis

On account of the earth rotating about its axis

How is acceleration due to gravity affected by rotation of earth about its axis ?

The rotation of the earth about its axis is periodic but not simple harmonic. Justify.

Statement I : Many great rivers flow towards the equator. The sediments that that they carry increase the time of rotation of the earth about its own axis. Statement II : The angular momentum of the earth about its rotation axis is conserved.
