Driven harmonic motion
... As the mass moves past the equilibrium postion, an increasing Fs acts to slow the mass as it moves to the left, stopping momentarily at x = -A, and then reversing directions. Motion is repeated symetrically between x = A and x = -A; if there are no nonconservative forces present, mechanical ener ...
