Investigating Air Resistance

Investigating Air Resistance: The Relationship surrounded by the fit out of Freefall and the lengthiness Length of a Helicopter DESIGN cosmos In this laboratory I am going to examine the relationship between the period of free fall of a paper whirlybird and the duration of the helicopter backstages. This result be done by written text the amount of beat each helicopter of different annexe length go away take to fall from a controlled height. Helicopters with bigger flee lengths allow consequentially induce larger advance areas in contact with the oxygenise during their free fall. Hence, helicopters in contact with more stock go forth be subjected to greater air resistance, meaning a delayed (larger) term of flight. This is a convey relationship between the two covariants. * Illustration not to scale Variables * The individual covariant is the wing length of the helicopter (centimeters) * The dependent variable 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 * corporeal structure helicopters will all be assembled the like way, with extend propellor facing upwards (see fig.

to a lower place), as to control the anxiety 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 Diagram of Expe! riment 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 being released...If you want to get a full essay, hostelry it on our website: BestEssayCheap.com
