CHAPTER 10 Angular Momentum; General Rotation
10-1 Angular Momentum—Objects Rotating About a Fixed Axis
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
10-6 Conservation of Angular Momentum
τ=0 , constant=L
the total angular momentum of a system remains constant if the net external torque acting on the system is zero
10-5 Angular Momentum and Torque for a Rigid Object
Lω = Iω
eg question: atwood's machine
bicycle wheel
torque required to keep an unbalanced system rotating.
10-4 Angular Momentum and Torque for a System of Particles ;General Motion
10-3 Angular Momentum of a Particle
the angular momentum of particle about a specified axis
L = r x p
10-2 Vector Cross Product; Torque as a Vector
C= |AxB|➡ABsinθ,
using determinant
τ=r x F
