effects of rotation and magnetic fields Flashcards
1
Q
Give 2 eqns for angular momentum
A
L = mvr = mwr^2 L = Iw
2
Q
whats the rotation rate of a cloud with radius R?
A
wr^2 = ΩR^2
3
Q
how does material fall into the cloud?
A
The rotational velocity decreases with increasing latitude, centrifugal forces decreases, only acts 90 deg to rotation axis.
-material concentrated into a disc like geometry
