The title of my investigation is how I can change the acceleration of a trolley?  


          The prediction of this investigation will be more mass, more acceleration and the more force the more acceleration.


         The method for this investigation will be:

   Firstly the trolley is rolled down the slope, making sure that the height of the slope is keeping the same. With this method it was hard to get accurate measurement of the acceleration that was because gravitational potential energy (G.P.E) will be applied in the results which is not needed.

        G.P.E= mass×height×gravity.

In method two elastic was used to push the trolley forward. The mass was changed and the measurement of acceleration was measured by the light gates.

Using elastic the investigation was still not successful because the force should have been kept the same, so that the trolley can accelerate. Working with the elastic only applies force for a very short time.

The results of the pulley gave us the accurate results. I will make a graph with a best line fit. The mass of the trolley will be plotted on the x-axis and the acceleration on the y-axis. Because I have got some accurate results I will not need to repeat this experiment. The results in

 I can terminate that friction must be acting at all times during the experiment. In this experiment I noticed that the force needed to keep an object moving steadily on a surface is equal to the forceful friction rate for the surface.

My conclusion to this experiment would be…

As increasing forces are applied to a constant mass, the acceleration of the mass also increases (F = ma).

  • The force needed to just start an object moving is equal to the static friction value for the surfaces.
  • The force needed to keep an object moving steadily (with constant velocity) on a surface is equal to the dynamic friction value for the surface.

My readings did not have any anomalous results which mean that my results were accurate.

Using an air track would give me the results a lot more accurate.

If I would carry out another experiment to improve my experiment I would keep the force acting on the trolley constant but change the mass of the trolley each time to further investigate the formula of F = ma

    I think the results were reliable none-the-less if the anomalies were ignored and a line of best fit was drawn on the graph. If I look back on my predictions and my hypothesis then I think I can safely say I was pretty much on the right track and I had correctly made my predictions.
