Why is it important?
The commentary highlights subtle differences between free and forced vibrations.
Perspectives
It was really interesting to find evidence in the commended article that free vibration differs from forced vibration in certain cases. Such differences remain largely unnoticed and could be critical in the understanding of vortex-induced vibration.
