How does speed affect stopping distance? I chose to release a car from the top of a hill and let it roll down, as the height of the ramp increases the speed of the car increases.

How does speed affect stopping distance? Height (m) Speed ^2 Speed (m/s) Mean stopping distance (cm) Range 0.01 0.2 0.45 13.4 1.5 0.02 0.4 0.63 26.7 1.5 0.03 0.6 0.77 40.6 2.0 0.04 0.8 0.89 55.6 2.5 0.05 1.0 1.0 66.1 1.0 0.06 1.2 1.69 74.7 3.0 Diagram of the experiment Conclusion From my graphs I have drawn I can see that there is a positive correlation between the speed and the stopping distance. ...read more.


This is because as the ramp gets higher the speed increases and as the speed increases so does the stopping distance. In conclusion, in response to the question 'how does speed affect stopping distance?' the answer is the faster the speed the longer the stopping distance. Evaluation There were a number of difficulties in getting these results. Because I was collecting the results this meant that there was quite a lot of human error. ...read more.


However given the circumstances and short time I was given to carry out this investigation I would say that my results were fairly reliable. I collected no outliers and the largest range of my results was 3.0cm. I am confident with my conclusion because I feel despite all the factors that could have gone wrong my results were reliable and made sense, and at the end of the day its common sense that the faster something travels the more distance it will cover to stop.

    Evaluation: The data that I collected was quite reliable, as there was a clear pattern visible on the graphs that I drew, so I think that I can draw a reasonably safe and reliable conclusion for the different masses that I tested.

    Since the potential energy of an object is directly proportional to its height above the zero position, a doubling of the height will result in a doubling of potential energy. A tripling of the height will lead to a tripling of potential energy.

    the height of the ramp correctly the person measuring the height may have gone slightly over or below the desired height, which we needed, as the metres rulers were slightly worn, and hard to distinguish where the marks were. To improve this we could have used brand new rulers, which

  1. Investigation into factors affecting the speed of a car rolling down a ramp

    The car will probably accelerate as it goes down the ramp so the length of the ramp will have an effect on the speed of the car, that is, if the car does not reach its top speed by the time it has gone down the ramp.

  2. Approximate Stopping Distances

    Instead the stopping is a function of physical forces, gravity and friction. Thinking distance is affected by many factors: The thinking distance is affected by the speed of travel because the faster the vehicle is travelling the longer it would take for the driver to think.
