To investigate forces, computer programs, and mapping software used in physics by measuring the acceleration of a rubber band powered car and calculating the maximum net force produced when gradually increasing the mass of the car.
There were three different hypotheses. One group hypothesized that the maximum net force would decrease when more weight was added. Another hypothesized that net force would increase to a point and then decrease once too much weight was added. And the final hypothesized that the net force would remain unchanged.
-Rubber Band Car
-Gram weights (10 to 200 grams)
Setup motion detector and SPARKvue software to record velocity and acceleration of a moving object
Measure winding distance 2 feet from the motion detector
Wind car from 2 feet
Begin recording data in SPARKvue
Do 2 trials and increase weight by 5, 10, or 50 grams
Repeat until 200 grams has been added
