Wait — maybe the rate is magnitude? But question says "rate of change".

Is the Rate of Change Really a Magnitude? Exploring the Core of Rates in Mathematics and Science When we talk about the rate of change, common intuition might suggest it’s about scale or magnitude—how quickly something grows or shrinks. But here’s a compelling question: Could the rate of change actually be a magnitude itself? At first glance, magnitude and rate of change seem distinct—one describes size, the other speed of change. Yet deep mathematical and physical insight reveals a hidden connection: the rate of change quantifies how magnitude evolves over time or space. In essence, it is a measure of change in magnitude. In calculus, the derivative captures the rate of change of a function—a number describing how drastically the output grows or decays at any given point. This isn’t just a numerical value; it’s the fundamental measure mapping changes in magnitude to measurable quantities.
