Data Analysis of Speed

From the start to meter 1, the speed of the car is increasing because the data point is higher than the previous data point.

From meter 1 to meter 2, the speed of the car is increasing because the data point is higher than the previous data point.

Project ConclusionWrite your project conclusion here. Be sure to answer the following questions: How were you able to maximize the forward force of the balloons? How did you minimize backward forces of friction and drag? What could you have done better to make your car go further and faster? How did your car perform compared to other cars in the class. What have you learned by doing this project?

WARNING FROM MR. G:

This file is a template and example of the PowerPoint you and your partner must create using YOUR data. Without effort in analysis using your own data, graphs, photos, and adjusting forces that apply to the motion of your car, YOU AND YOUR PARTNER WILL NOT RECEIVE CREDIT FOR THIS PART OF THE PROJECT.
