Helicopter Experiment

Prediction: As the mass on the helicopter’s 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 velocity for a paper helicopter is low.

Variables: Independent variable will be the mass that we change throughout the experiment. The dependant variable will be the time that we measure for the helicopter to reach the floor. Finally the controlled variables include, the helicopter itself. As well as the height from which the helicopter is released.

Apparatus: Paper, Scotch tape, Scissors, Ruler

Method: Create a helicopters rotors using take and paper use the diagram to help you

Diagram:

Apparatus: 2 meter rulers, one stop watch, one balance, 3 paper clips, pencil.

Method: 1) Using both the meter rulers and a pencil make a mark on the wall.
2) Weigh the helicopter then record its weight
3) Hold the paper helicopter parallel to the mark on the wall
4) At the same time release the helicopter and start the stopwatch
5) Stop the stop watch when the helicopter touches the ground
6) Weigh the first paper clip and record its weight
7) Attach the paper clip to helicopter and repeat the experiment
8) Weigh the second paper clip and record its weight
9) Attach the paper clip to helicopter and repeat the experiment
10) Weigh the final paper clip and record its weight
11) Attach the paper clip to helicopter and repeat the experiment
