Abstract

The objective of this essay is to analyze the data, gathered from the relevant experiments, in order to find if drag force depends on the shape of the objects. In this essay, we will be looking at different shaped and sized objects and how the drag force reacts to these differences in shape. For this research, these differences in shape can be classified as their differences geometric shape, mass and cross-sectional area. In order to reach the answer of our research, unique experiments were conducted for each difference in shape. Each object was hung in a contraption that consists of a cardboard wind tunnel, created by myself, that generated linear air flow via a hair dryer for the objects. Below you will find the diagram. The X angles, made possible by the forces, were used to find the drag forces. The angle is determined by an optical system, by the shadow of the string that the object hangs from the drag forces will be under the scope. These forces were compared with different shaped objects such as, sphere, cube and cylinder, in order to answer the question ‘’How do drag forces exerted on an object differ by geometric shape?’’. At the end of the trials and calculations, it was clear that the drag force that was applied to the spherical objects were smaller when compared with the other shapes and that as the cross – sectional area increases also the drag force increases. Additionally it was seen that as mass increased the angel decreased.
