The units in the animation are MKS (meters, kilograms, and seconds). The mass is 1 kg. The graph of Fourier terms displays only the lowest four harmonics. The Fourier approximation to the triangle function and the analytic solution also include only the first four harmonics.
Note: setting the forcing frequency to the resonant frequency AND setting the damping to zero will result in a divide-by-zero.
