Happy Breach Experiment

Design- In this experiment we selected the happy sack to use for our experiment, as this sort of ball doesn’t bounce when dropped to the ground and this then gives us more accurate data for us to compare with the theoretical time. To record the closest accurate time and distance we could get, the equipment we chose to use, were two stopwatches so that we could compare the human reaction times and a tape measure to correctly measure the distance that the ball is going to fall from; which counted down every 25cm. And the methods we used was keeping one variable the same, so the happy sack and changing another so the height, every 25cm.
Improvements- The improvements that could’ve made the experiment reach the theoretical time, could possibly be having less or even zero air resistance, since then we could accurately see how our …show more content…
Another error was air resistance for the reason that, it depends on two important factors - the speed of the happy sack and its surface area and so acceleration during a fall would be less, as air resistance affects the motion of the happy sack by slowing it down; we could even use a vacuum chamber as that has no air resistance and no elements that can interrupt our experiment; for instance air and wind. Lastly, heavier objects have less effect from air resistance, but however even if our happy sacks were slightly heavier compared to the other balls, our happy sack broke and so that made the happy sack considerably lighter than it initially started out.
Conclusion- In conclusion, the experiment results compared to the theoretical time aren’t exactly equal towards each other as predicted with the given equation of t=0.452 ×√ (distance fallen). As the data recorded was not accurate enough and did not match ties with the theoretical time as there were several systematic mishaps and
