Chapter 10: Rotation
2
Rotational Variables Radian Measure Angular Displacement Angular Velocity Angular Acceleration
3
Constant Angular Acceleration Are angular quantities vectors? Equations of motion for constant angular acceleration.
4
Kinetic Energy of Rotation (rotational inertia) (kinetic energy) System of Particles Solid Body
5
Rotational Inertia
6
Parallel-Axis Theorem Let h be the perpendicular distance between the given axis and a parallel axis through the center of mass. If I com 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
7
Torque Line of Action Moment Arm The ability of a force F to rotate a body depends not only on its tangential component F t, 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!
