Review of the World of Energy
The World of Energy courses, Physics 103 and 104, are a 10credit hour, two
quarter sequence.
The courses explore the basic principles of physics in the context of
energy use.
The courses include practical examples from everyday life to help you use
energy safely and wisely.
They help prepare you to make rational, informed decisions
regarding energy policy, the environment, and your own place in the changing World of
Energy.
Class Activities
During two, 2hour classes per week, your instructor will explain physics
concepts and introduce handson activities and demonstrations to illustrate these
concepts.
To help organize, understand, and remember the information from the
demonstrations and class activities, students complete and turn in activity sheets during
each class.
Activity sheets are found in Part I of the
Physics 104 Activity Book
.
Students must be present for the full class period to receive credit for an activity sheet,
unless excused by the instructor.
Lectures
In addition to attending two 2hour classes per week, students attend a 1hour
lecture.
At most lectures, you will see a video or hear a speaker discussing energy use.
These videos and lectures are an important part of the course.
They explain physics
principles and help relate these principles to the role of energy in everyday life. A list of
questions for each video is included in Part II of the
Physics 104 Activity Book.
These
questions help students identify important concepts in the videos.
Answers to these
video questions are not handed in.
Instead, students write and turn in a summary of
each lecture video of at least two paragraphs.
The dates and location of the lectures
are given in the course syllabus.
Midterm and final exams will include questions based
on the material in the lectures.
Examinations
Course examinations consist of two midterms of 30 questions each and a
comprehensive final examination of 45 questions.
All exam questions are multiple
choice.
Midterm exams are given during the lecture hour.
The dates of the
examinations are listed in the course syllabus.
No
makeup examinations will be given.
If you have a conflict with any of the exam times, notify your instructor immediately.

Students may use calculators during exams, but may not program them or use
their graphing capabilities.
Exams include a sheet with useful equations and constants.
Equation sheets are provided because the World of Energy emphasizes understanding
concepts, rather than memorizing equations and constants.
However, it is essential that
students understand the meaning of the equations, their symbols, and their units.
This is the end of the preview.
