                       Extra Credit: Include a photo of your car HERE

TASK 1 - Create a Distance vs. Time data table for your car. Only include 0-5 meter data.

                               Distance vs. Time Data Table
                             Time (seconds)    Distance (meters)
                                   0                   0




TASK 2 - Create a Distance vs. Time graph for your car. Only include 0-5 meter data.
                      Be sure to use scatter graph with lines in Excel.
TASK 3 - Create a Speed vs. Time data table for your car. Only include 0-5 meter data.

                                 Speed vs. Time Data Table
                  Distance (m)          Time (sec)         Speed (m/s)
                       0                     0                 0
                       1
                       2
                       3
                       4
                       5


TASK 4 - Create a Speed vs. Time graph for your car. Only include 0-5 meter data.
                      Be sure to use scatter graph with lines in Excel.
                         TASK 5 - Distance vs. Time Graph Analysis

  During this        Car is speeding up, slowing         Reason (look at the slope):
   distance:          down, or constant speed:

  0 to 1 meter


  1 to 2 meters


  2 to 3 meters


  3 to 4 meters


  4 to 5 meters




TASK 6 – Create 3 Energy Transfer Diagrams of the interactions involved when your car
was in motion.


                             ____________ Interaction


                                       Mechanical
                                       Energy Transfer




                  Decrease in                                     Increase in

                    Energy                                           Energy
           ____________ Interaction


                  Mechanical
                  Energy Transfer




Decrease in                           Increase in

  Energy                               Energy




           ____________ Interaction


                  Mechanical
                  Energy Transfer




Decrease in                           Increase in

  Energy                               Energy
TASK 7 – Create a Force Arrow Diagram for each 0m, 1m, 2m, 3m, 4m, and 5m. I will do
the 0m and 1m for you  Be sure to adjust the force arrows depending on the associated
forces.




                                     Forces at 0 Meters
                              At meter 0, the car is at zero speed.




                                          Forces are Balanced.


                                     Forces at 1st Meter
                               At meter 1, the car is speeding up.
           Force exerted by air on car.

                                                             Force exerted by balloon on car.
    Force exerted by axel on car parts.


   Force exerted by ground on wheels.




                   Forces are Unbalanced in the Forward Direction.
TASK 8 – Write a one-two paragraph conclusion that answers our project questions: What
balloon powered car design will have the greatest average speed over 5 meters? What
balloon powered car design will travel the greatest distance?
