fluxions

"In Newton's time, "fluxions" were used to describe the rate of change, much like we now use "derivatives" to understand how quickly a car's speed increases as it accelerates. "

"The fluxions of sand through the hourglass marked the passage of time during the game. "

"The fluxions in the classroom's temperature throughout the day were noticeable, shifting from cool in the morning to warm by the afternoon. "

"The spilled paint began to fluxions across the canvas, creating swirling patterns. "

"Newton's method of "fluxions" provided a powerful way to calculate the instantaneous rate of change, such as the speed of a car at a specific moment. "
