10-1 Angular Momentum—Objects Rotating About a Fixed Axis

10-6 Conservation of Angular Momentum

10-5 Angular Momentum and Torque for a Rigid Object

10-4 Angular Momentum and Torque for a System of Particles ;General Motion

10-3 Angular Momentum of a Particle

10-2 Vector Cross Product; Torque as a Vector

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
