PH.2 a-b - Mathematical Relationships
The student will investigate and understand how to analyze and interpret data. Key concepts include
a) a description of a physical problem is translated into a mathematical statement in order to find a solution; and
b) relationships between physical quantities are determined using the shape of a curve passing through experimentally obtained data.Bloom's Levels: Analyze; Understand
- I can determine how steep a roof must be so that snow is able to slide off.
- I can determine the impact a steep hill has on the average and instantaneous speed of a runner.
UNDERSTANDING THE STANDARD
The concepts developed in this standard include the following:
- Mathematics is a tool used to model
and describe phenomena.
- Graphing and dimensional
analysis are used to reveal relationships and other important features of data.
- Predictions are made from trends
based on the data.
- The shape of the curve fit to
experimentally obtained data is used to determine the relationship of the
- All experimental data do not
follow a linear relationship.
- The area under the curve of
experimentally obtained data is used to determine related physical quantities.
- Physical phenomena or events can
often be described in mathematical terms (as an equation or inequality).
In order to meet this standard, it is expected that students will
a-b) recognize linear and nonlinear relationships from graphed data.
where appropriate, draw a straight line through a set of experimental data points and determine the slope and/or area under the curve.
