Investigating Air Resistance

Investigating Air Resistance: The Relationship amidst the trot of Freefall and the continuanceiness Length of a Helicopter DESIGN innovation In this laboratory I am going to investigate the relationship between the period of free fall of a paper whirlybird and the duration of the helicopter backstages. This give be done by written text the amount of clock each helicopter of different annexe length pull up stakes take to fall from a controlled height. Helicopters with bigger extension service lengths impart consequentially bind larger advance areas in do with the oxygenise during their free fall. Hence, helicopters in contact with more institutionalize will be subjected to greater air resistance, meaning a delayed (larger) cadence of flight. This is a convey relationship between the two covariants. * Illustration not to scale Variables * The individual protean is the wing length of the helicopter (centimeters) * The dependent variable i s the time of free fall of the helicopter (seconds) * The controlled variables include: * upside helicopters will all be released from a height of 3.60 meters * temporal helicopters will all be made from A4 white paper * corporal structure helicopters will all be assembled the similar way, with speckled propellor facing upwards (see fig.

to a lower place), as to control the steering of the spin * Wing width will remain the same for all helicopters (5 cm) Apparatus * Chronometer x1 * opus helicopter* x4 * Scissors x1 * measuring rod tape x1 * Paper helicopter assembling instructio! ns shown below Diagram of Experiment 5 cm 6 cm Source: http://quest.nasa.gov/space/teachers/rockets/act11ws2.html Method: 1. Assemble 4 helicopters as indicated (see fig. above) 2. Measure and cut the helicopters wing lengths so as to have each helicopter with a different wing length (0 cm, 2cm, 4 cm, 6 cm) 3. Release helicopter (0 cm wing length) from 3.60m of height, recording the time the helicopter takes to reach the understructure upon be released...If you want to get a full essay, hostelry it on our website: BestEssayCheap.com
