Rotational KE: $K_{rot}$ = $\frac{1}{2}$I*$omega^2$

Work done by torque: W = tau * theta (for constant torque), or W = integral(tau * d(theta))

Work-Energy Theorem (rotational): $W_{net}$ = $\frac{1}{2}$I*$omega_f^2$ - $\frac{1}{2}$I*$omega_i^2$

Power: P = tau * omega

Analogy check: Every translational formula has a rotational twin — just replace m->I, v->omega, F->tau, s->theta, p->L.
