Helicopter Experiment EssayPrediction As the mass on the helicopters copters increases, the speed taken for the rotors to spin down faster, this is because there will be more downward pull from gravity, as the terminal fastness for a root helicopter is low.Variables Independent variable will be the mass that we change throughout the taste. The dependant variable will be the m that we measure for the helicopter to hap the floor. Finally the controlled variables include, the helicopter itself. As well as the top side from which the helicopter is released. Apparatus Paper, Scotch tape, Scissors, RulerMethod acquire a helicopters rotors using take and paper use the diagram to help youApparatus 2 meter rulers, one check out watch, one balance, 3 paper clips, pencil.Method1) Using both the meter rulers and a pencil make a mark on the wall.2) Weigh the helicopter then record its weight3) Hold the paper helicopter parallel to the mark on the wall4) At the same time release the h elicopter and start the stopwatch5) halt the stop watch when the helicopter touches the ground6) Weigh the first paper clip and record its weight7) Attach the paper clip to helicopter and fictionalize the experiment8) Weigh the second paper clip and record its weight9) Attach the paper clip to helicopter and repeat the experiment10) Weigh the lowest paper clip and record its weight11) Attach the paper clip to helicopter and repeat the experimentConclusion and EvaluationIn this experiment my farsightedness 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 by from the mark of 2m therefore it would have inaccuracies of around 10cm this causes the experiment results to vary. Another flaw be ing the human reaction time, which is pretty slow and inconsistent, this therefore allows us to stop the stopwatches at the wrong time making 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 solution for the wrong human reaction time could be good solved by the use of light 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 presently 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 from the experiment
