#### Course Description

#### Addendum to Course Description

This is a pre-calculus introductory physics course for pre-medical, pre-dental, pre-chiropractic and pre-physical therapy students and students working toward a degree. Topic of study is mechanics, and includes statics, forces and motion, energy, collisions, circular motion and rotation. This course meets college transfer, Oregon Block Transfer and program requirements as listed above.

#### Intended Outcomes for the course

After completion of this course, students will

1) Apply knowledge of linear motion, forces, energy, and circular motion to explain natural physical processes and related technological advances.

2) Use an understanding of algebraic mathematics along with physical principles to effectively solve problems encountered in everyday life, further study in science, and in the professional world.

3) Design experiments and acquire data in order to explore physical principles, effectively communicate results, and critically evaluate related scientific studies.

4) Assess the contributions of physics to our evolving understanding of global change and sustainability while placing the development of physics in its historical and cultural context.

#### Quantitative Reasoning

Students completing an associate degree at Portland Community College will be able to analyze questions or problems that impact the community and/or environment using quantitative information.

#### Course Activities and Design

Principles and techniques are presented through lectures and class demonstrations. Students must register for lecture and one laboratory. Laboratory work will be performed in order to clarify certain facts in the lecture material.

#### Outcome Assessment Strategies

At the beginning of the course, the instructor will provide a syllabus that details the methods used to evaluate student progress and the criteria for assigning a course grade. The methods may include one or more of the following tools: examinations, quizzes, homework assignments, laboratory reports, research papers, small group problem solving of questions arising from application of course concepts and concerns to actual experience, oral presentations, or maintenance of a personal lab manual. Specific evaluation procedures will be given in class. In general, grading will be based on accumulated points from homework assignments, tests, a final exam, and labs.

1.0 FUNDAMENTALS OF MEASUREMENT

The goal is to develop knowledge and skills in fundamentals of measurement.

Objectives:

1.1 Demonstrate the use of the metric system.

1.2 Introduce the concept of "significant figures."

a. in laboratory measurements

b. in calculations and problem solving

1.3 Use vectors in calculations

a. vectors and scalars

b. components of vectors (This includes a brief introduction to sine, cosine, tangent and their inverses, since these are not covered in the math prerequisite for this course.)

c. graphical solutions to vector problems

d. analytical solutions to vector problems
