Unit I Reading Graphical Methods
One of the most effective tools for the visual evaluation of data is a graph. The investigator is
usually interested in a quantitative graph that shows the relationship between two variables in
the form of a curve.
The following was a post to a newsgroup in 1992.
About 6-7 years ago, I was in a philosophy class at the University of Wisconsin,
Madison (good science/engineering school) and the teaching assistant was explaining
Descartes. He was trying to s
A graph is one of the most effective representations of the relationship between two variables.
The independent variable (one controlled by the experimenter) is usually placed on the x-axis.
The dependent variable (one that respo
Unit I Reading: Significant Figures
Laboratory investigations usually involve the taking of and interpretation of measurements. All
physical measurements obtained by means of instruments (meter sticks, thermometers,
electrical meters, clocks, etc.)are to
UNIT II READING: MOTION MAPS
A motion map represents the position, velocity, and acceleration of an object at various clock
readings. (At this stage of the class, you will be representing position and velocity only.)
Suppose that you took a stroboscopic p
UNIT IV: Reading - Force Diagrams
The analysis of a problem in dynamics usually involves the selection and analysis of the
relevant forces acting on some object under consideration. An important first step in this
analysis process is to carefully select t
Unit IV: Introduction to Vector Analysis
As you learned in the last unit, there is a difference between speed and velocity.
Speed is an example of a scalar: a quantity that has only magnitude. Velocity is an
example of a vector: a quantity that has both m
UNIT VII - ENERGY
(WITH LESS WORK)
The traditional approach to work and energy in a standard physics course often ends up being a
rather imprecise, confusing mass of equations and definitions, such as "energy is the ability to do
work" and W = .
