displacers
Objects causing movement
Displacers are things or people that push something out of its usual place or position.
In engineering, a displacer is a component that moves through a fluid to measure volume or transfer energy, as in certain engines or level sensors.
More broadly, anything that takes the space of something else—new technology displacing old, one population displacing another—is a displacer.
