angular momentum
L=Iω
using newton second laws
L=0=constant
Iω=Ioωo=constant
eg question:clutch
neutron star
running on s circular platform
spinning bicycle wheel
C= |AxB|➡ABsinθ,
using determinant
τ=r x F
the angular momentum of particle about a specified axis
L = r x p
Lω = Iω
eg question: atwood's machine
bicycle wheel
torque required to keep an unbalanced system rotating.
τ=0 , constant=L
the total angular momentum of a system remains constant if the net external torque acting on the system is zero
