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.


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 plotted quantities.
  • 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.
