It was also observed that air resistance can actually affect the metal ball’s direction and speed, since it fell away from the target most of the times. It was also observed that the shorter the displacement, then the effect of air resistance on the ball is lesser. As for the uncertainties, the absolute uncertainties were calculated for the average time and for the uncertainty time squared. However, for the displacement, the uncertainty was 0.03 which is over half the limit of reading (0.0005) because the measurement had to be taken from the metal clamp and the metal clamp was far away from the ruler and it was hard to measure it because it was above eye level at some points which means that the data might have not been read properly.
