"The truth is, when all is said and done, one does not teach a subject, one teaches a student how to learn it.  Teaching may look like administering a dose, but even a dose must be worked on by the body if it is to cure.  Each individual must cure his or her own ignorance.  Accordingly, all sound educational theory enjoins individual attention."
- Jacques Barzun


INFORMATION

This is the first semester of a three-semester, calculus-based physics sequence - Physics.  We will cover
    Vectors and scalar quantities, kinematics, Newton's Laws of Motion, work, work-energy, conservation of energy,
    conservation of momentum, center of mass and its motion;
rotational motion; conservation of angular momentum, gravity.
Pre-requisite: MA 241

SAMPLE SOLUTION 

Problem:
The catapult of an aircraft carrier accelerates a jet fighter from rest to takeoff speed of 173 mi/h in a distance of 307 ft.  Assume constant acceleration.
(a) Calculated the acceleration of the fighter in m/s2.
(b) Calculate the time required for the fighter to accelerate to takeoff speed.

  Solution    Note that all work is shown, a description of the work is given, and the final answer is boxed.

    QUOTES TO THINK ABOUT


The thinking of a scientist differs from that of a student.  The student wants to know facts: numbers, dates, results, things which might appear on the final exam.  How old is the universe? How distant is the Moon? How hot is the Sun's visible face? All these can be dug out of textbooks and encyclopedias, but they alone tell next to nothing about the science.  A scientist instead asks, What is the evidence?

- David Stern


Problems are the cutting edge that distinguishes between success and failure. Problems call forth our courage and our wisdom; indeed, they create our courage and our wisdom. It is only because of our problems that we grow mentally and spiritually. When we desire to encourage the growth of the human spirit, we challenge and encourage the human capacity to solve problems, just as in school we deliberately set problems for our children to solve. It is through the pain of confronting problems that we learn.
 - Morgan Scott Peck

I shot an arrow into the air,
It fell to earth, I knew not where
