Torque and Rotational Dynamics
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:
- Rotation and rolling →
Connect angular motion, torque, inertia, energy, and momentum to explain rotating systems and contact motion.
Model rotational motion, torque, equilibrium, and rotational inertia.
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 Kinematics ↗
Follow angular position, velocity, and acceleration through equations and graphs.
- Connecting Linear and Rotational Motion ↗
Connect angular motion to arc length, tangential speed, and acceleration.
- Torque ↗
Draw where forces act and use lever arms to predict turning effects.
- Rotational Inertia ↗
Compare mass distributions and calculate inertia about parallel axes.
- Rotational Equilibrium and Newton’s First Law in Rotational Form ↗
Balance forces and torques while distinguishing translation from rotation.
- Newton’s Second Law in Rotational Form ↗
Connect net torque, rotational inertia, and angular acceleration.
Put the unit together
The unit practice ends with 6 additional problems. Build the diagrams and explain the model before checking the separate reasoning and scoring criteria.
