    Romans 10:10, 11, 13

    10 for with the heart man believes,

    resulting in righteousness, and with the

    mouth he confesses, resulting in

    salvation.

    11 For the scripture says , Whoever

    believes in Him will not be

    disappointed. 13 for Whoever will call upon the

    name of the Lord will be saved.

    They are darkened in their understanding andseparated from the life of God because of theignorance that is in them due to the hardeningof their hearts.Eph. 4:18, NIV

    In christ we are able to know God personally.

    Our relationship with God through Christ is a

    cornerstone of our identity. . . . This

    relationship determines our perception of realityand subsequently our world view.

    Regal Books, 1990

    Why Study Physics?

    I need a science course to graduate!

    Physics is Phun!

    OKIt can be fun! The basic science.

    Appreciate Gods awesome universe

    Make informed decisions as a responsiblecitizen.

    Learn to think and question.

    Keys to Success

    Know the basics (ex: Newtons first law)

    Know the players (ex: Net force)

    Be a believer (ex: I can do this if I work at

    it!)

    Scientific Measurements

    Measurements are a hallmark of good science.I often say that when you can measure something and

    express it in numbers, you know something about it.

    When you cannot measure it, when you cannot express

    it in numbers, your knowledge is of a meager and

    unsatisfactory kind. It may be the beginning of

    knowledge, but you have scarcely in your thoughts

    advanced to the stage of science, whatever it may be.

    MathematicsThe Language of Science

    Integration of science and mathematics

    Eratosthenes 235 B.C.

    (Also see Figs. 1.2, 1.4, 1.5, 1.6) Ideas of science are unambiguouswhen

    expressed in mathematical terms.

    Equations of scienceprovide expressions ofrelationships between concepts

    Equations are guides to thinking.

    The Scientific Attitude

    The scientific attitude is one of

    inquiry.

    experimentation.

    willingness to admit error.

    being open to change (in response totruth)!

    The Scientific Attitude

    Scientists

    are experts at changing their minds.

    must accept experimental findings.

    test for erroneous beliefs

    understand objections and positionsof antagonists.

    The Scientific Attitude

    Fact: close agreement by competent observers (Data)

    Law: (principle) Statement about the relationship ofnatural quantities that has been tested over andover again and has not been contradicted.

    Hypothesis: an educated guess that must be tested.(Is there a test for proving it wrong?)

    Scientific Theory: synthesis of a large body ofinformation that encompasses well-tested and

    verified hypotheses about certain aspects of thenatural world.

    Scientific Methods

    There is no onescientific method (specifics).

    In general, scientific methods refer to principles and

    procedures for the systematic pursuit of knowledge

    involving the recognition and formulation of a problem,the collection of data through observation and

    experiment, and the formulation and testing of

    hypotheses.

    SCIENTIFIC METHODPoint: Correct testingis combined with

    observation and explanation(hypothesis). Produces a more accurate,

    more true conceptof what is actually happening!
