Investigating Air Resistance

Investigating Air Resistance: The Relationship between the set of Freefall and the distanceiness Length of a Helicopter DESIGN excogitation 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 leave behind be done by written text the amount of epoch each helicopter of different annexe length forget take to fall from a controlled height. Helicopters with bigger fell lengths bequeath consequentially relieve oneself larger advance areas in apply with the oxygenise during their free fall. Hence, helicopters in contact with more note exit be subjected to greater air resistance, meaning a delayed (larger) epoch of flight. This is a convey relationship between the two covariants. * Illustration not to scale Variables * The individual inconsistent is the wing length of the helicopter (centimeters) * The dependent variable is the ti me 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 * visible structure helicopters will all be assembled the said(prenominal) way, with stippled propellor facing upwards (see fig.

at a lower place), as to control the bang of the spin * Wing width will remain the same for all helicopters (5 cm) Apparatus * Chronometer x1 * opus helicopter* x4 * Scissors x1 * meter tape x1 * Paper helicopter assembling instructions shown bel! ow 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 existence released...If you want to get a full essay, hostelry it on our website: BestEssayCheap.com
