Movement is created by using energy to push or pull an object forward, backward, up or down from its original position. In some cases, the energy that is used is only a small amount and the speed created is low. In other cases, the energy amount that is needed for movement is high. In all cases, the expenditure of energy creates additional responses. The more parts that are involved in the movements, the more likely that some vibration is to be expected. However, that vibration can interfere with the working of the machine or application and may cause serious problems. While the designers assume that there will be some vibration, there are other factors that can increase the rate of vibration. The age of the machine and the sum of its parts, its overall weight (including when in use) or the way that it is used, can increase vibration. That increased vibration can then cause fatigue, breakdown or premature failure.
