Description | ||
This science fair project aims to ascertain how the shape of a car affects the amount of wind resistance that arises when the car is in motion. The experiment is carried out using polyfoam cut outs of various shapes - rectangular, low profile rectangular and low profile streamlined in order to compare how much wind resistance each shape experiences. | ||

1. The independent variable of this science fair project is the shape of the object – rectangular, low profile rectangular and low profile streamlined. The dependent variable is the wind resistance on the object. This is measured using the Newton spring balance. The constants (control variables) are the wind velocity, the materials used to construct the shapes (poly foam), the smoothness of the table surface and the distance of the fan from the object. 2. Using a paper knife, the following shapes are carved from the poly foam. a. A cuboid – 100mm x 100mm x 200mm b. A ..... |
