SCI 202: Physics of Modern Technology I

Overview

This course examines items of modern technology, including clocks and musical instruments to understand their behavior based on the underlying principles of physics. You will learn how the world around us is predictable, once you develop quantitative problem-solving skills. Easily understood visual models assist in attaining a conceptual understanding of physics and its application to the real world. This class continues with SCI203.

Goals and Principles

The general goals of this course are to:

• Provide an interesting course that covers physics
• Enable you to see science in everyday life
• Show how modern technology and the world around us are predictable (rather than incomprehensible)
• Develop quantitative problem-solving skills.

The two guiding principles behind the design of the course are:

• Everyone understands concepts best by seeing them in action and thinking about them, rather than by hearing those concepts explained.
• Understanding that physics (and solving problems that test that understanding) is a learned skill, like playing golf or the violin. It takes time, effort, and practice to master such a skill.

Prerequisite Knowledge

You must be competent in basic algebra to understand the material and solve problems, but no math beyond algebra will be used. Specifically, you need to be comfortable with basic algebraic operations, such as:

• Isolating and solving for the unknown quantity in an equation exponents
• Scientific notation
• Basic rectangular-coordinate graphing

Additionally, you should be familiar with the metric system of measurement.

Tools for Success

SCI202 features a Math Primer to aid you in understanding the mathematical concepts used throughout the course.

Likewise, access to a scientific calculator will be helpful — there are a number of calculators available for free online.

Learning Outcomes

Upon successful completion of this course, students will be able to:

• Explain many everyday phenomena and technologies in terms of basic physics principles.
• Apply that understanding to predict and explain behavior in novel situations.
• Evaluate whether proposed technologies are possible or not, according to the laws of physics.

Specific performance outcomes for the course are:

• Quantitatively predict the motion of objects and the forces required to move them under a variety of conditions.
• Predict the behavior of simple electrical circuits as they are used in several technologies such as incandescent lights, heaters, electric power generation, and electric power distribution.
