... expected if acceleration due to gravity is constant - as a straight line shows constant acceleration. The velocity values from smaller distances appear to be anomalous, suggesting some error involved in the experiment. This could be because any errors in height make up a larger proportion of the overall distance the mass had fallen when dropped from lower heights. Due to the fact that the object seems to be moving with a constant acceleration I have next decided to explore this value acceleration of the falling mass due to gravity. I believe this figure will be most accurately obtained through graphical methods by working out the gradient of a line of best fit, as fluctuations/slightly anomalous points (and therefore error) have been reduced over the large range. I plan to use two different graphs whose gradient is equal to acceleration in order to verify the answer. The simplest graph where the gradient ...
