| 释义 | aerodynamics (once / 53482 pages) n In physics, aerodynamics is the study of how things move through air. Car engineers consider aerodynamics when they design the shape of a vehicle. Aerodynamics is both the science of the way air moves, and also simply the way an object's shape affects how it moves through the air. Much of the design of airplanes focuses on the aerodynamics of their wings and noses, keeping them aloft and moving quickly through the air. The word aerodynamics has been around since the mid-1800s, combining the Greek prefix aero-, "air," and dynamics, a word applied to many branches of physics, from the Greek dynamikos, "powerful." WORD FAMILYaerodynamic: aerodynamically, aerodynamics USAGE EXAMPLESHe said he will tweak aerodynamics factors like the suit’s amount of surface area and the shape of the wing. Wall Street Journal(Dec 05, 2016) “Today, we are sitting on 50 years of progress on aerodynamics, fuel economy, design,” he said. Los Angeles Times(Dec 03, 2016) Formula One's rules are also changing in 2017, with bigger tires and new aerodynamics to make the cars faster and more aggressive-looking.
