Helicopter Experiment Essay Example for Free

whirlybird Experiment EssayPrediction As the plenty on the helicopters copters increases, the speed interpreted for the rotors to spin down faster, this is because there will be much downward pull from gravity, as the final stage velocity for a reputation helicopter is low.Variables Independent variable will be the mass that we transplant through go forth the try. The dependant variable will be the time that we measure for the helicopter to reach the floor. at last the controlled variables include, the helicopter itself. As well as the height from which the helicopter is released. Apparatus Paper, Scotch tape, Scissors, Ruler manner Create a helicopters rotors using take and paper use the diagram to help youApparatus 2 mebibyte rulers, one stop watch, one balance, 3 paper clips, pencil.Method1) Using both the meter rulers and a pencil make a hybridizing on the wall.2) Weigh the helicopter then unload its exercising weight3) Hold the paper helicopter parallel to the m ark on the wall4) At the same time release the helicopter and start the stopwatch5) Stop the stop watch when the helicopter touches the commonwealth6) Weigh the first paper clip and record its weight7) Attach the paper clip to helicopter and repeat the experiment8) Weigh the second paper clip and record its weight9) Attach the paper clip to helicopter and repeat the experiment10) Weigh the final paper clip and record its weight11) Attach the paper clip to helicopter and repeat the experimentConclusion and EvaluationIn this experiment my prediction was right, therefore proving that the helicopter may reach its terminal velocity faster with higher mass meaning that the speed is greater therefore it allows the helicopter to reach theground faster if there is more mass.There are two major flaws in this experiment, the first being the height from which the helicopter is dropped, as it is held away from the mark of 2m therefore it would have inaccuracies of around 10cm this causes the experiment results to vary. Another flaw being the kind reaction time, which is pretty slow and inconsistent, this therefore allows us to stop the stopwatches at the wrong time reservation the experiment inaccurate.If more time was available, a string could have been hung from the ceiling as a mark of height therefore allowing us to accurately drop the helicopter from the same height, rather than dropping it from an *estimated* 2m. The ascendent for the wrong human reaction time could be easily solved by the use of arc gates. The liht gates could be placed on the floor, and when the helicopter lands, the light will be disrupted therefore allowing the sensor to accurately measure the time taken for the helicopter to reach the ground.The graph is showing us that the speed and mass of a helicopter are directly proportional as when mass increases so does speed. However the graph had not been a perfect straight line, this could have been caused by the two inaccuracies pointed out fro m the experiment
