Lets back to my picture



My question

below we have ZERO angular momentum ?

V1<---Mx
......i
......i
......i
......o
......i
......i
......i
......Mx---->V1

No - please use right hand rule

below we have ZERO angular momentum ?

V1<---Mx
......i
......i
......i
......o
......i
......3*Mx ---->V1

No - please use right hand rule


below we have ZERO angular momentum ?

Mx ---> V

YES






please imagine below two situations



A)

m ..........<----m
i
i
i rope
i
i
i
i
Earth


B)
m...........<----m



in situation B 100 % energy will be exchange

in situation A XX% wil take mass m
and YY% will take Earth ( radial force )
