Videos (Directly from ApPhysicsLectures.com)

- video F1: Rotational Kinematics. This video explains rotational kinematics for constant angular acceleration.
- video F2: Rotational Kinematics (part 2). This video continues to explain rotational kinematics and details how the linear quantities are related to rotational (or angular) quantities as an object rotates.
- video F3: Rotational Kinematics (part 3)
- video F4: Torque and the Cross-Product (or Vector Product): This video explains a little bit about torque and the cross-product or vector product of two vectors. So this is the second way that two vector quantities can be multiplied together.
- video F5: Torque and the Cross-Product (part 2)
- video F6: Torque and the Cross-Product (part 3)
- video F7: Static Equilibrium Problems. This is a video that explains the necessary conditions for keeping a structure in static equilibrium. Static equilibrium occurs when a system has no linear acceleration and no angular acceleration.
- video F8: Static Equilibrium Problems (part 2)
- video F9: Rotational Inertia or Moment of Inertia. This video introduces the concept of rotational inertia (or rotational sluggishness or moment of inertia)
- video F10: The Parallel-Axis Theorem. If you know a system's rotational inertial about an axis that passes through its center of mass, then you can find the rotational inertial about a second axis that is parallel to the original axis by using the parallel-axis theorem.
- video F11: Rotational Dynamics (Newton's Second Law in Rotational Motion)
- video F12: Rotational Dynamics (part 2)
- video F13: Rotational Dynamics (part 3): This is a video that details Atwood's machine problems where the pulley has significant mass.
- video F14: Rotational Kinetic Energy (part 1)
- video F15: Rotational Kinetic Energy (part 2)
- video F16: Angular Momentum
- video F17: Angular Momentum (part 2)
- video F18: Unit F Review (part 1). This video is a review of the concepts covered in unit F on Rotational Motion. Try pausing the video after each question to see if you can answer the question on your own.
