A1 practical: Rolling ball example results
In this experiment the velocity of a ball was measured by analysing a video of its motion. Below is an example of the graph obtained for a slope height of 2.7cm. In this way the velocity was measured for the ball rolling down the same slope from different heights. The data has been entered into the table below. The uncertainty in height is estimated from the accuracy of the ruler. 0.2mm was decided upon because it...
