Energy conservation in a co-rotating or accelerating frame depends on the specifics of the frame's rotation and acceleration. To assess energy conservation, one must calculate the Lagrangian in terms of the generalized coordinates of the non-inertial frame. If the Lagrangian is not explicitly time-dependent, the associated Hamiltonian is conserved, which can be interpreted as the system's energy. In uniformly rotating frames, energy conservation can be expressed through a specific equation involving conservative forces. Overall, the ability to determine energy integrals hinges on the time dependence of the Lagrangian.
