Understand Torque
Calculate torque using tau = rF sin(theta). Practice identifying lever arms, finding torque directions with the right-hand rule, and computing net torque.
Master Moment of Inertia
Calculate I for point masses and know I formulas for common shapes. Apply the parallel axis theorem.
Apply Newton's Second Law for Rotation
Solve problems using tau_net = I*alpha. Connect rotational dynamics to translational dynamics in combined problems.
Solve Static Equilibrium Problems
Apply both equilibrium conditions (net force = 0, net torque = 0). Choose strategic pivot points and draw extended free-body diagrams.
Analyze Angular Momentum Conservation
Apply L = I*omega conservation in collisions, deformations, and systems with changing moment of inertia.
Master Rolling Motion
Apply v = R*omega, energy conservation with rotational KE, and the rolling race analysis for different shapes.
