Topic 9: Angular Momentum; General Rotation
Angular Momentum—Objects Rotating About a Fixed Axis
Angular momentum
Same direction if symmetrical object rotating about asymmetry axis
Angular velocity
Newton's 2nd law
Vector Cross Product; Torque as Vector
Torque
Cross product
Can obtained by using determinant of matrix
Direction can determined by Right-hand rule
Torque is maximum when
F
and
r
are perpendicular each other
Angular Momentum of a Particle
Angular Momentum
Angular Momentum and Torque for a
System of Particles; General Motion
angular momentum of a system of particles can change only if
there is an external torque
torque due to internal forces cancel
Angular Momentum and Torque for a
Rigid Object
Angular momentum
Conservation of Angular Momentum
Total angular momentum of a system remains constant if external torque =0
since
