WebbForced vibrations as the name implies, happens when an object is forced by an input force (periodic in nature) to vibrate at a certain frequency. Objects that are free to vibrate have their natural frequencies in which they vibrate when left for a duration of time. Resonance occurs when objects are forced to vibrate at their natural frequency.
