decelerating
Gradually becoming slower
Decelerating means slowing down—reducing speed or rate of change.
A car decelerates when the driver eases off the gas or applies the brakes.
The term applies beyond physical motion: Economic growth is decelerating, The project's momentum is decelerating.
The opposite of accelerating.
