This represents the object slowing down or decreasing its velocity.
Sometimes, you may be asked to add numbers to the dot diagram. For example, if an object moves rightward with a speed of 4 meters per second for 5 seconds, you would draw dots 4 meters apart and label them with the positions at each second.
Here's a second example: an object moves left at 3 meters per second for 6 seconds starting at the 12 meter mark. Start by drawing a number line and placing the starting dot at 12 meters. Then, add dots every meter towards the left, labeling them with the positions and times as you go.
We have answered the questions of what a dot diagram is and how it can be used to describe constant speed and changing speed motion. We have also learned how to draw vector diagrams for these types of motions.
Now, let's move on to the action plan. First, I would like to ask for your help. If you liked the video, please hit the like button below.

Here's the action plan to solidify your learning. We recommend trying out our concept builders on our website. There are two in particular that might interest you: motion diagrams and dots and graphs. These concept builders require drawing velocity vector diagrams and will help reinforce your understanding.
If you have the Minds On Physics app, you can also practice the oil drop representation, which is another term for dot diagrams. Look for the kinematic concepts module and the mission called oil drop representations.
Lastly, you can visit our website and check out the physics tutorial section. Lesson number two is a review of the concepts covered in this video.
We hope you enjoyed this video and we invite you to come back for more. Thank you!
