Helicopter Experiment: Speed of Fall

Helicopter Experiment Speed of FallHend DarwishResearch QuestionAt what drive on forget the chopper fall by adding more cover clips to its base (the bottom)? inconstantsIndependent Variable Amount of paper clipsDependent Variable SpeedConstant aforesaid(prenominal) HelicopterSame TimerSame height (2m)HypothesisMy theory is that the more paper clips added to the base of the helicopter, the promote forget increase.I think this will happen because gravity will pull the helicopter down and the opposite force (air resistance), which is acting on the wings will get weaker because the wings will fold upwards. This will cause less for the air resistance to act on which will cause the speed to increase.Method For our helicopter lab, we first meacertain(p)d deuce meters on the wall so we support will drop the helicopter at the aforementioned(prenominal) place. Then, Eliah will drop the helicopter and Holly will metre how long it takes with the stopwatch. We repeated this step for thre e mores tests and with two, three, four, five and six paperclips connect to the base. Then, we found the mediocre speed of each paperclip and recorded our results into a graph.To bring forth our test a fair test, we do sure its the same person time and dropping the helicopter. Also, we always dropped the helicopter from two meters.For our safety, we made sure that we are in an empty space so we dont setback into anyone or the paper helicopter doesnt go on someones head. Also, we made sure that we are not next to any chemicals or flamed Bunsen burner so when we pick up our helicopter, it wont catch on fire or be covered by any chemicals that could harm us.Apparatus1 newsprint HelicopterStopwatch100cm ruler6 paperclipsDiagram selective information CollectionAmount of Paper Clips on a HelicopterThe cadence of paper-clips on the helicopter Time taken for the helicopter to fall a blank space of two meters (s) attempt 1Trial 2Trial 3MeanSpeed(m/s)11.381.681.311.451.3821.221.401.1 91.271.5731.131.401.301.271.5741.161.01.091.051.95.961.30.841.031.946.63.53.81.653.08Data Processing Table of Amount of Paper Clips Affect the Average Speed of the Paper HelicopterThe amount of paper-clips on the helicopter Time taken for the helicopter to fall a distance of two meters (s)Trial 1Trial 2Trial 3Mean Average Speed (m/s)11.381.681.311.451.3821.221.401.191.271.5731.131.401.301.271.5741.161.01.091.051.95.961.30.841.031.946.63.53.81.653.08 To get the mean, you have to add the three trials unitedly then divide it by three. For example1.83 + 1.68 + 1.31 =4.374.37 / 3 = 1.45 To get the speed, you have to divide 2 by the mean of the three trials. For example2 / 1.45 = 1.382 / 1.27 = 1.57Data Presentation ConclusionAccording to our graph our hypothesis was correct The more paper clips added to the base of our helicopter the more the speed will increase. Our data corresponds with the line of best fit really nearly up until our last data point which was 6 paper clips and was 3.08s. It is ofttimes higher than all the other points, I think this one concomitant piece of data is unreliable because it dose not correspond to the succor of the data as well as the graph. This may be because our timing methods when timing the last one was different then the rest of our graph. To make sure that this would be an perfect experiment, we did three trials for each paper clip(s) and then calculated the mean and speed.Evaluation Our Method was reliable and extremely accurate because for each amount of paper clip, we had three trials so we could create an average speed. Also, we used the same person for timer and the dropper of the paper helicopter.If I could re-do the experiment, I would have made the height higher, such as 3-4m so we could have more accurate readings.
