Calculate the angular speed of the Earth due to its spin (rotational motion).

Answer»

Data : T = 24 hours = 24 × 60 × 60 s

Angular speed, \(\omega\) = \(\frac{2\pi}T\) = \(\frac{2\times 3.142}{24\times 60\times 60}\) = \(\frac{3.142}{43200}\)

= 7.273 x 10-5 rad/s

The angular speed of the Earth due to its spin (rotational motion) is 7.273 × 10-5 rad/s.
