Summary of findings
The more weights the hydrogen car carries, the speed of the car would decrease and the rate acceleration would also decrease.
For the future design of hydrogen car, more considerations should be made to ensure that the car travels at a constant speed. Failure to do so would mean that the car might accelerate too quickly suddenly. Due to human error, the driver might not be able to stop in time and might in turn cause an accident.
The conversion of hydrogen to electricity should be made more reliable as the car might come to a stop unpredictably thus this might cause accidents, etc.
Between 1 and 2 weights, there was a sudden drop of acceleration. This shows that the car should stick to the proportion of 2g of hydrogen used for 50 weight for maximum potential.
Also we can conclude that the maximum weights the car can hold is about 8 weight as it came to a stop at that amount of weight.
Areas for further studies
Further studies could be made on how other factors could affect the performance of the car. An example would be a study in aerodynamics. Aerodynamics is the way air moves around things (NASA, 2013). Studying the motion of air around an object allows us to measure the thrust and drag of the car (How Thing Fly, 2014). Most of us don't think of air or wind as a wall. At low speeds and on days when it's not very windy outside, it's hard to notice the way air interacts with our vehicles. But at high speeds, and on exceptionally windy days, air resistance (the forces acted upon a moving object by the air -- also defined as drag) has a tremendous effect on the way a car accelerates, handles and achieves fuel mileage (George, P. E. , 2014).
