**Definition of the distance of an object :**

Distance is the difference between the final and initial position of an object.

**Definition of the speed of an object:**

The speed of an object is the rate at which the distance changes in a given period of time.

**Instantaneous Speed:**

The speed at any time, assumed to be a time interval of zero.

**Acceleration:**

Acceleration is the rate at which speed changes in a given period of time.

**Optimization:**

Optimization is determining the combination of variables or factors that result in an extreme being produced.

**Newton****’s Method:**

Newton’s Method is a strategy for approximating the zero of a function that uses the tangent line approximation of a point on a curve to iterate closer to a zero.

**Differential:**

Differential is format for expressing a derivative that has many practical applications.
