Vector Addition (Distance and Displacement)
https://phet.colorado.edu/en/simulation/vector-addition
*Place check marks next to the following:
X Show Sum
X Show Grid
*Create some sort of path using at least 4 red vectors. Make sure that they are situated/added "end to end."
1. Do the red vectors show distance or displacement?
2. Does the green vector show distance or displacement?
3. What does |R| represent?
4. What does θ represent?
5. What does Rx represent?
6. What does Ry represent?
*Create a scenario where distance and displacement are exactly the same.
*Create a scenario where displacement is equal to zero.
Stickman Graph Game (this will be collected during the next class period)
https://davidwees.com/graphgame/
*Follow the link above. Do the following for all 12 of the graphs:
-Use the stickman to produce a graph that is as close as possible to the red line.
-Describe the motion using specific time intervals on a piece of notebook paper OR on a Google Doc. Complete sentences are NOT needed.
Ex. Puzzle #1:
0-14 seconds - no motion
Ex. Puzzle #3:
0-4 seconds - constant speed FORWARD
4-14 seconds - no motion
Random Homework Collection (Motion Graphs 1 to Motion Graphs 6)
https://camillasenior.homestead.com/motion_graphs.pdf
*Follow the link above. Note that the page numbers are in the upper right-hand corner of the pages.
*Read over the included packet and answer any questions that are asked on notebook paper OR on a Google Doc (do not use the same piece as the Stickman Graph Game).
*Some pages only contain examples and not problems.
*You do NOT need to recopy the questions. INSTEAD, include the page number that they are on for organizational purposes.
PHET Moving Man (Simulation, Long)
https://archive.cnx.org/specials/e2ca52af-8c6b-450e-ac2f-9300b38e8739/moving-man/
Example Problem
*Select "Charts +" from the top left of the screen. Change the position to -10 meters, the velocity to 8 meters per second, and the acceleration to -1.5 meters per second squared.
*Check the "Show Vector" boxes for velocity and acceleration.
*Press the record button (near the bottom middle of the page). Stop recording once the Moving Man is at a distance of 8 m.
*Hide the acceleration graph.
*Select "Playback" and replay the motion if needed.

Distance-Time vs. Speed-Time Graphs (Video, Short)
Ch. 1 Exam Review (Answer Key).pdfOptional Assignment
Consider the following scenario. The object is always moving forward unless indicated otherwise.
An object starts at rest (0 seconds, 0 meters). It begins by speeding up for 5 seconds. It then moves at a constant speed for 12 seconds. After this time, it slows down until it comes to a complete stop, which takes 7 seconds. It then moves in reverse at a constant speed for 6 seconds until it reaches its original starting point, where it suddenly stops.
Opportunity #1: Draw the object’s distance-time graph. (+1/4 per correct section = +1 point maximum)
Opportunity #2: Draw the object’s velocity-time graph. (+1/4 per correct section = +1 point maximum)
The graph(s) must include the following:
*Titles for both the x- and y-axes.
*Increments and units for the x-axis only. Having these on the y-axis is not necessary.
*A logical/easy-to-read scale and construction.
*Correct shapes/direction for each increment.
*The graph(s) must also be hand-drawn on graph/grid paper.
