Angular displacement, velocity, acceleration — the rotational analog of linear kinematics.
How force produces rotation; the condition for rotational equilibrium.
Rotational inertia — how mass distribution about an axis resists angular acceleration.
Newton's second law for rotation — net torque drives angular acceleration.
Energy of a rotating body, and its role in energy conservation.
Combined translation and rotation; the rolling constraint v = ωr.
Without external torque, L is conserved — that's why a skater spins faster with arms in.
