decelerators
Things that slow
Decelerators are devices or mechanisms that slow something down.
The term appears most often in technical contexts—engineering, aerospace, automotive—where precise speed reduction matters: The spacecraft deployed its decelerators during atmospheric entry.
Anything that reduces velocity or rate of change can be called a decelerator, including braking systems, parachutes, or drag-inducing surfaces.
