CHAPTER 10 : Angular Momentum; General Rotation
10-2 Vector Cross Product; Torque as a Vector
c =
Properties of vector :
10-3 Angular Momentum of a Particle
L = r x p
10-4 Angular Momentum and Torque for a System ofParticles; General Motion
dL / dt = ∑ τext
dLcm / dt = ∑ τcm
10-5 Angular Momentum and Torque for a Rigid Object
Angular momentum, Lω = Iω
system that is rotationally
imbalanced will not have its angular momentum and
angular velocity vectors in the same direction.
A torque
is required to keep an unbalanced system rotating.
10-1 Angular Momentum—Objects Rotating About a FixedAxis
L = I ω
Unit : kg m2 s−1
Newton's 2nd law
∑τ = dL / dt = d(Iω) / dt = [(I1ω1) - (I2ω2) ] / dt
Torque
T = r . F
10-6 Conservation of Angular Momentum
dL / dt = 0 & L = Constant
∑ T = 0
The total angular momentum of a system
remains constant if the net external torque acting on the system is 0.
