  The effects of Lorentz and CPT violations on macroscopic objects are
explored. Effective composite coefficients for Lorentz violation are derived in
terms of coefficients for electrons, protons, and neutrons in the
Standard-Model Extension, including all minimal and nonminimal violations. The
hamiltonian and modified Newton's second law for a test body are derived. The
framework is applied to free-fall and torsion-balance tests of the weak
equivalence principle and to orbital motion. The effects on continuous media
are studied, and the frequency shifts in acoustic resonators are calculated.
