Constant Angular Acceleration
Are angular quantities vectors?
Equations of motion for constant angular acceleration.
Parallel-Axis TheoremLet h be the perpendicular distance between the given axis and a parallel axis through the center of mass. If Icom is the rotational inertia of the body about the parallel axis that extends through the body’s center of mass, then the rotational inertia I about the given axis is
Torque
Line of Action
Moment Arm
The ability of a force F to rotate a body depends not only on its tangential component Ft, but also on just how far from the pivot point the force is applied.
The unit of the torque is Nm! Do no use J!
Work and Rotational Kinetic Energy
Work–kinetic energy theorem
Work, rotation about fixed axis
Work, constant torque
Power, rotation about fixed axis
