In vibration analysis, displacement refers to the measure of how far a vibrating object moves from its rest position during its oscillation. This definition encompasses both the maximum distance the object travels from its equilibrium position and the direction of that movement. Understanding displacement is crucial because it provides insights into the amplitude of the vibration, which is directly related to the severity of any potential issues within the systems being analyzed.

Distance covered can imply a general measurement of movement but lacks the specificity that displacement provides in the context of vibrations, which requires attention to the position relative to rest. The rate of speed focuses more on how quickly something moves, rather than the extent of that movement, and frequency of oscillation pertains to how often the vibrations occur rather than the distance of movement itself. Hence, the choice emphasizing how far something is moving captures the essential aspect of displacement in vibration analysis.
