Energy and Momentum of Rotating Systems
Find these readings by topic
This earlier reading list remains available with its complete tasks. The current book places these resources in the following topic chapters:
- Circular motion and gravitation →
Explain curved motion using real radial forces and connect gravitational fields with circular orbits.
- Energy, work, and power →
Track energy stored and transferred through work, dissipation, and power within a stated system.
- Momentum and collisions →
Use system momentum and external impulse to analyze interactions, then judge collision models from energy evidence.
- Rotation and rolling →
Connect angular motion, torque, inertia, energy, and momentum to explain rotating systems and contact motion.
Analyze rolling, rotational energy, angular impulse, and angular momentum.
Use the sections below to build the models in this unit. The AP course lessons provide topic-specific instruction and practice; companion readings offer additional explanations and original interactive quizzes.
- Rotational Kinetic Energy ↗
Build rotational kinetic energy from the motion of the system’s parts.
- Torque and Work ↗
Read torque–angle graphs and connect rotational work to energy transfer.
- Angular Momentum and Angular Impulse ↗
Connect angular momentum, angular impulse, and torque graphs.
- Conservation of Angular Momentum ↗
Choose a rotating system and explain speed changes when its shape changes.
- Rolling ↗
Compare rolling, slipping, translation, rotation, and energy transfer.
- Motion of Orbiting Satellites ↗
Connect satellite motion to gravitational energy and angular momentum.
