Developing a Christian Perspective in Physics

All of creation testifies to God and so it should be no surprise that Physics, by exploring the physical world, also explores God's relationship with creation and us. In this course, we will take time to look at how the laws of the natural world are a reflection of the relationship between Creator and Creation. Clearly our task is to develop skills and understandings but we should also be able to look "beyond" these and see how and where ideas come from.

Evaluation

Assignments

Read this carefully! There will be two kinds of assignment - each with its own purpose:

  1. Daily Assignments: You will be expected to hand in at the start of each class two worked questions from the chapter we will discuss during that class. These questions do three things: they encourage you to read your text!, they reward you for doing this and they provide me with feedback on how you are doing. Your grading will consist of two steps:

    initial attempt Your initial solutions will be graded on a 0 - 5 point scale:
    0 =
    no effort
    1 =
    poor effort, major errors
    2 =
    fair effort with modest conceptual errors or good effort with major conceptual errors
    3 =
    good effort with minor conceptual errors or fair effort with only minor errors
    4 =
    good effort with only minor errors
    5 =
    good effort with no errors
    correction You will receive your initial attempts the following class with a minimum of comments and a numerical score. The solutions to these questions will be posted at this time! You may receive up to 2 additional points if you correctly identify your mistake and correct it in a different color. You must clearly identify the error (explain what you did wrong not merely rephrase the posted solution!). You have up to (but not exceeding) one week to hand in your corrections.

  2. Weekly Assignments: Every 10 days (or so) you will have a major assignment that reviews material from previous classes!

 

Unit Exams:

Unit C October 20, 2017; 2:00 pm - S210
Unit N November 24, 2017; 2:00 pm - S210

 

Final Exam

A final exam, based on the entire course (units C and N) will be scheduled for December.

 

Your final grade in the course will be comprised of both lecture and lab marks. The weighting is as follows:

Unit exams (2)

30%

assignments

25%

final exam (1)

20%

lab reports/exercises

25%

   

Your final grade will be expressed using the alpha grade system used by The King's University College. See student calendar for more information

Note: you must pass the lab section of the course in order to pass the course. 

Content Outline: Physics 241

  1. Physics 241 will serve as a general level entry to college physics. Some calculus will be introduced as needed. The principal focus of the course will be the application of Newton's laws to diverse situations. Major topics considered will be:
  1. Conservation laws: The laws of conservation of energy and momentum will be developed. These laws will be introduced as fundamental concepts in modern physics.
  2. Rotational Motion: the rotational analog of Newton's laws will be developed. This will lead to a discussion of the physics of extended bodies.
  3. Vectors: the idea of directed quantities (vectors) will be introduced with applications involving kinematics in two and three dimensions. This will include a treatment of trajectories in a uniform gravitational field.
  4. Work and Energy: the work-energy relations will be explored and lead to the concepts of kinetic and potential energy in conservative systems.
  5. Newton's Laws: Newton's laws will be developed as unifying principles relating kinematics and dynamics to the physical world. The concept of force will be developed with applications to motion, circular motion and friction.
  6. Gravitation: Newton's laws will be applied to circular motion and lead to the development of Newton's formulation of the Universal Law of Gravitation. Applications will include Kepler's laws of planetary motion and simple orbital motion.

In addition to the topics discussed above, the historical and cultural dimension of the ideas of physics will, where appropriate, be explored. This will lead to discussions relating one's worldview to one's physics (i.e. relating the Newtonian world view to modern determinism).

 

Physics 241 Laboratory Outline

Physics 241 consists of both lecture and laboratory activities. Laboratories will be based upon context-rich, collaborative learning situations. Lab activities will consist of:

 

Collaborative Groups

Recent educational research shows that students, working in collaborative groups, achieve significant benefit in both skill development and understanding. Throughout the term you will be assigned to a working group of three or four students (these will change during the term). All lab submissions are to be done as a group project. In some cases groups will be responsible for the design and implementation of experiments. All student initiated labs must be approved by both the instructor and the special projects coordinator - Ms. C. Slupsky.

Rich Context Problem Solving

A component of the lab activities and some assignment problems will be the introduction of rich context problems. These are complex problems that more closely mirror "real-life" situations and will require group effort to solve. In some cases the problems will be designed to motivate a specific laboratory investigation. 

Laboratory Objectives

There are a number of key objectives for this section of the course:

  1. increased understanding of the role of experiment in gaining knowledge
  2. the design of experimental procedures
  3. introduction to the use of computer interfaces in data collection
  4. use of the spreadsheet in the analysis of data
  5. introduction to the principles of error analysis
  6. experience working in collaborative settings
  7. enhanced problem solving skills

Written Lab Work

Your participation (and eventual grade received) will be made up of a series of items:

The emphasis will be to make the lab experience useful and enjoyable and to enhance your learning of physics. The lab topics are listed in the course syllabus.
