In a broader sense, decelerate can also be used metaphorically to describe a decrease in the intensity, pace, or urgency of something. For instance, a person may decelerate their work pace when they take a break or pause to relax and rejuvenate. In economics, deceleration refers to a decline in the growth rate of an economy or its key indicators, such as gross domestic product (GDP) or investment.
Overall, decelerate is a term used to indicate a reduction in speed, pace, or intensity. Its applications can range from the physical realm, like cars and planes slowing down, to the metaphorical realm, depicting the reduction of pace or progress in various domains.
