Observation 1:

Was the car in steady and stable motion throughout?  
YesYesNo
Observation 2:

Was the car moving in a straight line mostly?
YesYesYes
Observation 3:

Did lever and string operate smoothly as well as expected?
NoYesNo
State 1 area for modification.
Type of string/rope usedWheels in position with the axelUsage of "Joints"
State rationale(s) for the above proposed
modification.
We needed to use a rope which could create more tension/friction so that the force is not too powerful for the car to move and not start off with a jerky movement.The wheels had to be positioned perpendicularly with the axel so that they do not make the whole structure unstable and when the whole structure is unstable, the car would not move.We realised that we should not be using "joints" as it just contributes to making the whole structure inefficient as they would bear most of the force, and if the "joints", in this case corks, breaks, the whole car would not move.

All modifications should be clearly documented along with rationales and photographs.

Total Score= 70-10+2(3.65)-2(5.7-1)=57.9 (revised)
