The rotational speed of Earth at this latitude is seven-seven-eight.
The total, however, of the rotational moment of momentum of the system barely reaches two per cent.
What, then, is the effect of the rotational velocity of the surface of the earth on the atmosphere near to it?
This rotational motion is also found in the nebul and star clusters as well as in the stars and planets.
It is important to distinguish between two types of strain: the “rotational” type and the “irrotational” type.
At the same time the tidal influence of the earth was lessening the rotational movement of the moon.
He also showed29 that this “rotational elasticity” can be produced by certain hidden rotations going on in the medium.
Hence in order to keep up the rotational momentum, which as we have seen must remain constant, the mass must rotate quicker.
We spiralled down around it, looking for a landing place and trying to match our speed with its rotational velocity.
Searching problems and discussion are instigated at once, and the notion of rotational equilibrium and force moments brought in.
