Investigating Helicopter Fall Rates: Impact of Wind and Water on Descent Speed

This investigation explores how different factors, including the number of paper plates used and the amount of water on helicopter wings, influence the speed at which a helicopter descends. By dropping paper helicopters from a height of 150 cm, we measure their fall rates while manipulating the independent variables of wing plates and water. This experiment seeks to understand the relationship between these factors and the flight dynamics of lightweight helicopters, offering insights into aerodynamics and environmental effects on falling objects.

  1. How fast can a helicopter fall ? By: Galilea, Isabel, Karla, Yareli

  2. Group’s question : How does the type of wind materialand the amount of water ona wing affect how fast the helicopter hits the ground ?

  3. Hypothesis: If amount of plates_______ (inc/dec) and amount of water _______ (inc/dec) , then the velocity of the helicopter falling _______ (inc/dec).

  4. Independent and dependent variables, constants/controls Independent variable: the amount of platesand the amount of water in a wing. Dependent variable: how fast the helicopter falls into the ground. Constants/Controls: The size of the helicopter , the heightwhere we are dropping it from.

  5. Materials Materials : • Paper plates (2) • paper helicopters (2) • Spray bottle (water) • timer • meter stick Procedure : • Gather materials • Build helicopter • Find the height (150cm) we are dropping it from. • start trial1( 0, 1 or, 2 paper plates)by spraying the helicopter3 times and place fan above 150 cm • Repeat steps for the helicopter that isn’t wet • record data

  6. Data table:
