Rotation and rolling
What students will learn
Connect angular motion, torque, inertia, energy, and momentum to explain rotating systems and contact motion.
Before this topic
- Circular motion and force diagrams
- Work and energy conservation
- Linear momentum and impulse
Read and connect
Read: Rotational Kinematics →
Represent angular position, velocity, and acceleration with equations and graphs.
Read: Connecting Linear and Rotational Motion →
Connect angular motion with arc length, tangential speed, and acceleration.
Read: Torque →
Draw application points and lever arms to predict torque.
Read: Rotational Inertia →
Compare mass distributions and calculate rotational inertia about specified axes.
Read: Rotational Equilibrium and Newton’s First Law in Rotational Form →
Check force and torque balance separately for rotational equilibrium.
Read: Newton’s Second Law in Rotational Form →
Connect net torque and rotational inertia to angular acceleration.
Read: Rotational Kinetic Energy →
Build rotational kinetic energy from the motions of the system’s parts.
Read: Torque and Work →
Use torque-angle area to connect rotational work and energy transfer.
Read: Angular Momentum and Angular Impulse →
Connect torque-time area and angular momentum change to angular impulse.
Read: Conservation of Angular Momentum →
Track external angular impulse when a rotating system changes its shape.
Read: Rolling →
Use contact-point motion to distinguish rolling without slipping from sliding.
Read: Motion of Orbiting Satellites →
Bring gravity, energy, and angular momentum together to analyze satellite motion.
Check understanding
Use the complete prompt to make student reasoning visible, then consult the separate worked reasoning and criteria. A reading completion tick records reading history.
Judge an angular-momentum conservation claim →
Compare possible angular-momentum intervals and propose a coast-down control for bearing drag.
Diagnose rolling and slipping →
Identify contact slip, predict friction’s translational and rotational effects, and state the extra information needed to compare total energies.
