In calculus, 'rate' refers to how something changes over time or with respect to another variable. It quantifies how much one quantity changes relative to another quantity.
Measures how much a quantity changes on average over an interval by dividing the total change in that quantity by the length of time or distance covered during that interval.
Instantaneous Velocity: Describes an object's velocity (rate of change in position) at an exact moment in time rather than an average over an interval.
Indicates how rapidly a population, investment, or other variable increases over time. It is a measure of the percentage change in the quantity over a specific period of time.
