**Physics 321**Hour 39-40 Final Review**Wednesday 8-10 am(or 11 am)**• Be on time! • Classroom • Counts 25% of the total grade! When, Where, etc.**Tests 1 &2**• Review Materials • Concentrate on basic material and new material What to Study**8-10 problems**• About ½ are qualitative, ½ are quantitative • Some will probably finish by 8:30 am. What to Expect**Basic force/torque problems + drag, Lorentz**• Basic Lagrangian • Lagrange Multiplier • Hamiltonian • Potential Energy • Solids: Inertia tensor, finding principal axes and principal moments • Solids: Euler’s equations, Euler’s angles, constants of motion, precession-spin-nutation Problems I**Coupled Oscillators: Lagrangian in Matrix form, finding**normal modes and frequencies • Chaos: No repeated motion, sensitive to initial conditions, harmonics, state space, frequency doubling in onset to chaos • Scattering: cm, solid angle, impact parameter, finding cross sections, definitions Problems II
