Applications of Linear Functions
Students take a look at applications of linear functionsCopyright 2004 Microsoft Corporation, One Microsoft Way, Redmond, WA 98052-6399 USA. All rights reserved.
This final lesson in the unit culminates with the Go Public phase of the legacy cycle. In the associated activities, students use linear models to depict Hooke's law as well as Ohm's law. To conclude the lesson, students apply what they have learned throughout the unit to answer the grand challenge question in a writing assignment.
The engineering applications that are useful to graph can be represented in a variety of ways. Particularly of interest is direct variation, which is the form many engineering applications take, including Hooke's law and Ohm's law. Electrical engineers use Ohm's law frequently for it states the most basic relationship between voltage, current and resistance. It is used in almost all calculations to analyze and test circuits in any electrical piece or equipment or device.
After this lesson, students should be able to:
- Explain some of the linear relationships that exist in the real world, including Hooke's law and Ohm's law.
- Revisit and respond to the challenge question.
