# PH.2 b-c - Graphically Represented Relationships

The student will **investigate** and**
understand** how to analyze and interpret data. Key concepts include

b) relationships between physical
quantities are determined using the shape of a curve passing through
experimentally obtained data; and

c) the slope of a linear relationship is calculated and includes appropriate units.

**Bloom's Levels:** Analyze; Understand

### BIG IDEAS

- I can determine the impact a steep hill has on the average and instantaneous speed of a runner.
- I can determine how much money I will need to buy any quantity of an item.

### UNDERSTANDING THE STANDARD

The concepts developed in this standard include the following:

- 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.

### ESSENTIALS

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.

c) use dimensional analysis to verify appropriate units.
