Unit 4 Introduction to Modeling

The rate with respect to time at which an object travels over distance. It is a scalar quantity.

• velocity

• average speed

• distance

• displacement

1. When used in the context of design: the use of a computer to assist in the process of designing a part, circuit, building, etc. When used in the context of drafting: the use of a computer to assist in the process of creating, storing, retrieving, modifying, plotting, and communicating a technical drawing.

• concept modeling

• component

• computer aided design or computer aided drafting (CAD)

Listing or mapping the concepts involved in a design or process under investigation.

• concept modeling

• computer modeling

• mathematical modeling

The change in position of an object from its starting position to its final position. Displacement is described by a magnitude and direction. Displacement is a vector quantity.

• domain

• displacement

• function

A measure of how far an object has traveled from its starting point regardless of its starting or ending position. Distance is a scalar quantity.

• domain

• distance

• follower

Representing information in the form of charts, graphs, maps, or geometric figures.

• model

• mock-up

• graphical modeling

The process of choosing and using appropriate mathematics and statistics to analyze empirical situations, to understand them better, and to improve decisions.

• mathematical modeling

• computer modeling

• concept modeling

A model or replica of a machine or structure for instructional or experimental purposes. Also referred to as an "appearance model".

• prototype

• scale model

• mock-up

A visual, mathematical, or three-dimensional representation in detail of an object or design, often smaller than the original.

• function
• model
• pattern

A physical representation of an object. Prototypes and appearance models are physical models.

• mock-up

• graphical model
