vibration is the motion of the body during which it moves to & fro about its mean position.while shm is a type of period motion here the restoring force is directly proportional to the displacement.
On free vibration the beam or structure is not suffering influence of forces (Beam on space). In forced vibration the structure is under presence of force example bridges. Later on will you discover the free vibration is important to obtain natural frequencies and mode shapes. the difference b\w forced and free vibration can be understand by the examples.............a) the vibration of a pendulum is free vibration which needs no external force to vibrate. b) the vibration of a machine like a drill is forced vibration which needs an external force to vibrate.
Forced vibration: If a system is subjected to an external force, the resulting vibration is known as forced vibration if the frequency of the external force coincides with one of the natural frequencies of the system, a conditions known as resonance occurs (large oscillation). Failures of such structures as building, bridges, turbines and airplane wings have been associated with the occurrence of resonance.Damped vibration: Ifanyenergy is lost or dissipated in friction or other resistance during oscillation, the vibration is damped vibration.
If you mean molecular vibration than this is called "heat" and gives the object its current temperature.
longitudinal vibration is a form of wave pattern which produces alternative compression and rarefraction
vibration is the motion of the body during which it moves to & fro about its mean position.while shm is a type of period motion here the restoring force is directly proportional to the displacement.
There are a number of forces that could cause vibration in a ship. Friction for example is a force known to cause vibration.

mainly two types of Vibration measurement: shaft vibration Bearing Vibration
A vibration in the air
A phenomenon that occurs when the frequency of a force applied to a system matcches the natural frequency of vibration in a system, resulting in a large amplitude of vibration.
Border Patroll
In the case of automotive dampening, it is the process of reducing sound or the force of vibration.
If you mean molecular vibration than this is called "heat" and gives the object its current temperature.
force of vibration over come the binding
the force apply on string it vibrate this vibration is called tension of the string
