About This Chapter
Rotation & Angular Momentum - Chapter Summary
This chapter can help you review physics concepts related to momentum, including the conservation of angular momentum, the moment of inertia and rolling motion. The concepts of rotational motion and constant angular acceleration are also introduced, as well as the parallel-axis theorem and the perpendicular-axis theorem. Additional lessons cover the kinetic energy of rotation and the relationship between torque and angular momentum. This chapter will prepare you to:
- Solve problems using rotational kinematics equations
- Calculate displacement using an equation
- Describe how constant angular acceleration works
- Explain how the parallel-axis and perpendicular-axis theorems work
- Detail how torque and angular momentum relate to each other
- Use conservation of angular momentum to solve problems
- Discover the moment of inertia
