Drag Coefficient

The drag coefficient is a numerical value that quantifies the resistance an object faces as it moves through a fluid, like air or water. It helps determine how aerodynamic or hydrodynamic an object is. A lower drag coefficient means less resistance, making it easier for the object to move, which is crucial for cars, airplanes, and boats. Factors like shape, surface texture, and speed influence it. Engineers use the drag coefficient to improve designs for efficiency, performance, and fuel economy, ultimately enhancing safety and sustainability in transportation.
