Pronunciation: [kˌə͡ʊɪfˈɪʃənt ɒv dɹˈaɡ] (IPA) 
The coefficient of drag is a measure of how much resistance an object experiences in a fluid environment. There are a variety of terms that can be used as synonyms for this concept, including drag coefficient, aerodynamic drag, and air resistance factor. Other terms that are sometimes used include form drag, pressure drag, and skin friction coefficient. No matter which term is used, the concept remains the same: the coefficient of drag provides a quantitative way to describe the amount of energy that is required to move an object through a fluid medium, taking into account factors such as the object's shape, size, and speed.
