The difference quotient is a measure of the average rate of change of the function over an interval (in this case, an interval of length h). [7] [8] : 237 [9] The limit of the difference quotient (i.e., the derivative) is thus the instantaneous rate of change.
Jerk (physics) In physics, jerk (also known as jolt) is the rate of change of an object's acceleration over time. It is a vector quantity (having both magnitude and direction). Jerk is most commonly denoted by the symbol j and expressed in m/s 3 ( SI units) or standard gravities per second ( g0 /s).
Rate of change may refer to: Rate of change (mathematics), either average rate of change or instantaneous rate of change. Instantaneous rate of change, rate of change at a given instant in time. Rate of change (technical analysis), a simple technical indicator in finance.

Relative change. In any quantitative science, the terms relative change and relative difference are used to compare two quantities while taking into account the "sizes" of the things being compared, i.e. dividing by a standard or reference or starting value. [1] The comparison is expressed as a ratio and is a unitless number.
t. e. In finance, the duration of a financial asset that consists of fixed cash flows, such as a bond, is the weighted average of the times until those fixed cash flows are received. When the price of an asset is considered as a function of yield, duration also measures the price sensitivity to yield, the rate of change of price with respect to ...
In mathematics, a rate is the quotient of two quantities in different units of measurement, often represented as a fraction. If the divisor (or fraction denominator) in the rate is equal to one expressed as a single unit, and if it is assumed that this quantity can be changed systematically (i.e., is an independent variable), then the dividend (the fraction numerator) of the rate expresses the ...
Momentum is the absolute difference in stock, commodity: Rate of change scales by the old close, so as to represent the increase as a fraction, "Momentum" in general refers to prices continuing to trend. The momentum and ROC indicators show trend by remaining positive while an uptrend is sustained, or negative while a downtrend is sustained.
