COURSE OUTLINE
PHY 105 PHYSICS 105 MECHANICS
Credit Hours: Four
Prerequisites: MAT 161 or POI
Catalog Description:
The first course of a calculus-level sequence in general physics, primarily for engineering
students or for students majoring in the physical sciences. Kinematics and dynamics of a
particle, Newton’s Laws of Motion, work and energy, momentum, rotational motion,
periodic motion, gravity, and fluid mechanics. Three class hours and three laboratory
hours.
LEARNING OBJECTIVES:
1. Students must be able to demonstrate a basic understanding of the concepts
and principles of mechanics by correctly stating the definitions of fundamental
terms and by clearly expressing physical laws and principles.
2. Students must demonstrate and ability to select and apply the appropriate laws
and principles of mechanics to a wide variety of specified problem situations.
This calls for insight, discrimination and analysis.
3. Students must be able to formulate in mathematical terms appropriate relations
and conditions that pertain to relatively complex physical problems, using
appropriate techniques of mathematical analysis, and they must be able to
follow through with the computational solution.
4. Students must be able to apply the principles taught in the classroom to
laboratory situations. This includes making accurate measurements,
performing mathematical and graphical analysis of measured values, and
reporting the results of the laboratory measurements in a comprehensible
written report.
