What are the different types of vibration, and what are their characteristics?

Question

Accepted Answer

There are two types of vibration - free and forced. Free vibration occurs when a system oscillates on its own, while forced vibration occurs when an external force is applied to the system.

Free vibration occurs when a system is disturbed and then allowed to oscillate on its own without any external force acting on it.
Forced vibration occurs when an external force is applied to a system, causing it to vibrate at a specific frequency.
Free vibration can be observed in a simple pendulum or a tuning fork, while forced vibration can be observed in a car engine or a washing machine.
Other types of vibration include damped vibration, where the amplitude of the vibration decreases over time due to energy loss, and undamped vibration, where the amplitude remains constant over time.
Vibration can also be classified as linear or nonlinear, depending on whether the system's response is proportional to the applied force or not.
