9th Journal Entry

9-3-10

Today we proved that our new propulsion system works, it traveling 5 meters in a total of 5 seconds and 14 miliseconds. Our estimation of the meters traveled was 4 meters, so we believe the car did excellent. The three variables of this experiment are mass being the controlled, spring force used being our independent variable and our dependent was the distance traveled. The force of our car was 119.33N and our car was 277.5 grams in total. In the making of this experiment we used Newton's 3rd, as our propulsion system is pushing springs together and using thier spring force to power our car. Newton's 3rd law states for every action their is an equal and opposite reaction.
