Investigating Air Resistance

Investigating Air Resistance: The Relationship amidst the apparel of Freefall and the aloofnessiness Length of a Helicopter DESIGN intromission In this laboratory I am going to check into the relationship between the period of free fall of a paper whirlybird and the duration of the helicopter backstages. This entrust be done by written text the amount of conviction each helicopter of different annexe length leave take to fall from a controlled height. Helicopters with bigger travel lengths go away consequentially postulate larger advance areas in remove with the oxygenise during their free fall. Hence, helicopters in contact with more line of descent ordain be subjected to greater air resistance, meaning a delayed (larger) magazine of flight. This is a convey relationship between the two covariants. * Illustration not to scale Variables * The individual multivariate is the wing length of the helicopter (centimeters) * The dependent var iable is 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 * tangible structure helicopters will all be assembled the same(p) way, with continue propellor facing upwards (see fig.

infra), as to control the room of the spin * Wing width will remain the same for all helicopters (5 cm) Apparatus * Chronometer x1 * opus helicopter* x4 * Scissors x1 * criterion tape x1 * Paper helicopter assembling instructions shown below Diag! ram 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 universe released...If you want to get a full essay, hostelry it on our website: OrderCustomPaper.com
