# Graphing Motion Unit 8 Graphing Motion Unit 8 AC What is the purpose of a graph? Graphs are a common method to visually illustrate relationships in the data. The purpose of a graph is to present data that are too numerous or complicated to be described adequately in the text and in less space. www.ncbi.nlm.nih.gov/pmc/articles/PMC4078179/ Graphs are a graphic or image of a data set or sets

We use graphs to help our reader understand the relationship between data without having to read each piece of datum. What does this graph tell you? Activity #1 Walk the Grid 1

This graph shows us the motion of someone walking. 1. Use the grid pattern of tiles on the floor to replicate this graph. 2. Walk the same motion as indicated on this graph. 3. What information can be derived from this graph? 4. Write down the meaning of each line segment on this graph.

NOTES ON POSITION or DISTANCE vs TIME GRAPHS Moving Man PHET Physics Classroom Activity #2 Walk the Grid 2

Walk a path within the grid you have established on the floor and create a matching graph. Activity #3 Grid 3 This graph shows us the motion of someone in motion. 1. Use the grid pattern of tiles

on the floor to replicate this graph. 2. Reproduce this same motion as indicated on this graph. 3. What information can be derived from this graph? 4. Write down the meaning of each line segment on this graph.

1. What is happening between 9AM and 11AM? 2. What do you think bicyclist is doing between 11AM and 1PM? 3. What was the total distance covered by 11AM, 1PM, and 4PM? 4. What was the average velocity (speed) of the bicyclist between 9Am and 11AM? 5. What was the average velocity (speed) over the entire trip?

QUIZ: Analyzing Motion Graphs 1. Where is the object demonstrating positive acceleration (speeding up)? 2. Where is the object demonstrating negative acceleration (slowing down)? 3. Where is the object demonstrating zero acceleration? 4. Where is the objects acceleration between 8 & 12 seconds? 5. What is the overall acceleration during this

trip? A= Vf-Vi t
