Graphical Analysis

1.3 Create and interpret graphs of 1-dimensional motion where acceleration is constant.
a. Represent data and relationships between variables in charts and graphs.
b. Use appropriate technology (such as graphing software, etc.) and other tools
S1S4
3. Explain diagrams and charts that represent relationships of variables.
Poor

Unclear reasoning, no evidence of graphical analysis. Misconception.
Matches p-t graph to v-t graph 1/3 times
Fair

Either initial velocity or acceleration not correctly obtained from graphs.
Calculation of acceleration correct.
Matches p-t graph with v-t graph 2/3 times
Good

Position-time and velocity time graphs analyzed correctly; Initial velocity found from y-intercept of vt graph
Acceleration found from slope of vt graph
Matches p-t graph to v-t graph 3/3 times
Mathematics

SIS3. Analyze and interpret results of scientific investigations.
2. Use mathematical operations to analyze and interpret data results.
1. Present relationships between variables in appropriate forms.
Poor

One kinematic equation listed. Sloppy or unclear work. No variable form attempted. Incorrect problem solving. Missing or incorrect units
Fair

Two kinematic equations known. Partial success solving kinematic problems. Partial success with algebraic derivations, all work not clearly shown.
Attempted variable form for all equations. Units included and correct.
Good

3 kinematic equations known; Distinguishes between displacement, distance, velocity, speed, and acceleration. Solves problems involving displacement, distance, velocity, speed, and constant acceleration.
Successful algebraic derivations with all work shown.
Data Presentation

2. Use mathematical operations to analyze and interpret data results.
Poor

Unmarked, unclear or missing data.
Fair

Some missing labels from tables/graphs. Best fit analysis appropriate to physical situation. Theoretical points not indicated on p-t graph
Good

Tables and graphs clearly marked including units. Best fit analysis appropriate to physical situation.
Theoretical points plotted on p-t graph
Preliminary Analysis (section 3)

S1S3
1. Present relationships between variables in appropriate forms.
Poor

Variables incorrectly identified. Understanding of physical relationships not reflected in analysis.

Testing Equations (section 4)

Poor

Unclear or missing work.
Fair

No evidence of comparison of theory to experiment. Application of kinematic equations to predict motion developing.
Good

Theoretical prediction made and compared to experimental data.
All work shown.
