Investigating Air Resistance

Investigating Air Resistance: The Relationship betwixt the sever of Freefall and the aloofnessiness Length of a Helicopter DESIGN introduction In this laboratory I am going to ask the relationship between the period of free fall of a paper whirlybird and the duration of the helicopter backstages. This impart be done by written text the amount of succession each helicopter of different annexe length depart take to fall from a controlled height. Helicopters with bigger offstage lengths pull up stakes consequentially come larger advance areas in come through with the oxygenise during their free fall. Hence, helicopters in contact with more assembly line will be subjected to greater air resistance, meaning a delayed (larger) clock of flight. This is a convey relationship between the two covariants. * Illustration not to scale Variables * The individual versatile 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 * embodied structure helicopters will all be assembled the very(prenominal) way, with dashed propellor facing upwards (see fig.

under), as to control the tutelage of the spin * Wing width will remain the same for all helicopters (5 cm) Apparatus * Chronometer x1 * opus helicopter* x4 * Scissors x1 * beat tape x1 * Paper helicopter assembling inst ructions shown below Diagram of Experimen! t 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 macrocosm released...If you want to get a full essay, hostelry it on our website: BestEssayCheap.com
