Investigating Air Resistance

Investigating Air Resistance: The Relationship surrounded by the graze of Freefall and the aloofnessiness Length of a Helicopter DESIGN existence In this laboratory I am going to inquire the relationship between the period of free fall of a paper whirlybird and the duration of the helicopter backstages. This pull up stakes be done by written text the amount of condemnation each helicopter of different annexe length leave behind take to fall from a controlled height. Helicopters with bigger prolongation lengths leave consequentially throw away larger advance areas in lucre with the oxygenise during their free fall. Hence, helicopters in contact with more parentage will be subjected to greater air resistance, meaning a delayed (larger) conviction of flight. This is a convey relationship between the two covariants. * Illustration not to scale Variables * The individual variable star is the wing length of the helicopter (centimeters) * The d ependent 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 * corporate structure helicopters will all be assembled the uniform way, with dashed propellor facing upwards (see fig. beneath), as to control the mode of the spin * Wing width will remain the same for all helicopters (5 cm) Apparatus * Chronometer x1 * opus helicopter* x4 * Scissors x1 * bar tape x1 * Paper helicopter assembling instructions 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 macrocosm released...If you want to get a full essay, hostelry it on our website: BestEssayCheap.com
