What's the use of 960fps slow motion photography on Samsung S9?

Samsung S9/S9+ camera supports slow motion mode: turn on the camera-click the gear icon-edit the camera mode-rear camera-slow motion-check, slide the mode above the screen when shooting, and select slow motion.

At the same time, the camera also supports the freeze-time shooting function, which can shoot at 960 frames per second in ultra-slow motion.
