Understanding Motion - The Walking Person Graphs
To start our motion unit, we use a brief introduction involving drawing simple graphs of a person walking in the classroom. These graphs draw out common misconceptions associated with drawing position graphs.
Modeling Motion Through Motion Graphs
The consistent model used to describe motion in physics is the motion graph stack or kinematic stack. This set of graphs includes position-time, velocity-time and acceleration-time descriptions. Any information regarding a motion event is coded on these graphs.
Logger Pro Commands
The document shown is a list of commands and directions for using Logger Pro. One side contains a list of common simples actions for Logger Pro. The other side contains step-by-step instructions for:
Creating PVAT graph stacks
Using the Video Analysis feature
The question always arises regarding analyzing videos taken using a phone vs a dedicated video device. Some students can make this work while others struggle with the extra steps involved.

Kinematic Stack Problems - Once students have a clear understanding of the motion that creates a specific kinematic stack, and the meaning behind the parts of a kinematic stack, we can deal with theoretical kinematic stacks.

This is where the first 80% Quiz occurs for the unit. This quiz covers matching PVAT graphs to motion, determining motion parameters from graphs, and kinematic stacks.

Full Lab Report - Racing Usain Bolt
The purpose of this lab is to determine differences in running patterns between student runners and Usain Bolt. These differences will be plotted out and analyzed using a kinematic graph stack.
Questions:
What specific differences occur between the running styles of a high school student-athlete and Usain Bolt?
What kinematic graph patterns indicate these differences?
"If-Then-Due-To" Hypothesis: "If a student-athlete's running pattern is plotted against Usain Bolt's running style, then specific differences can be determined based on kinematic graph differences."
Variables: (x) time; (y) position
Constant: same trial distance (50m)
Control: Usain Bolt data

Skeptical Questions In Science
The skeptical question topic for this unit is time. Skeptical questions are thoughtful "Why-based" questions which address biases in scientific material. This type of question is not seeking scientific facts.
The article associated with this unit is listed below:
Kinematic Formulas
Kinematic Formulas
The next logical step after kinematic graph stacks is to translate graphs to formulas. This results in the four most common kinematic or motion formulas in physics.
As we go through this unit, please be aware of and understand the differences in VARIABLES. For instance, depending on the website or resource, distance maybe listed as "d", "x", or "s".

The skeptical question/evaluation portion is left blank because there are multiple ways to answer the question. The Logger Pro answers are:
Velocity = 23.69m/s
Total Distance = 87.5m
Acceleration = 4.9m/s/s
