空气阻力(Air resistance)是指物体在空气中运动时所受到的阻力,该阻力的大小与物体运动的速度和形状等因素有关。
以下是一篇关于空气阻力的英文范文,供您参考:
Air resistance is the force that opposes the motion of an object in air. It is a type of frictional force generated by the interaction between the object and the air molecules. The magnitude of air resistance depends on the speed of the object, its shape, and the viscosity of the air.
When an object moves through air, its motion generates a pressure difference between its front and back sides. This pressure difference creates a force that tries to slow down the object's motion. If the object is moving fast enough, this force can become significant and even counteract the force of gravity, causing the object to lose altitude or even fall back.
Air resistance is a common phenomenon in many sports and activities involving flying objects, such as kites, airplanes, rockets, and drones. Understanding air resistance and its effects on the motion of these objects is crucial for optimizing their performance and ensuring their safety.
空气阻力(Air resistance)是指物体在空气中运动时所受到的阻力,该阻力与物体运动的速度的平方和物体的形状有关。

Air resistance
Air resistance is the force that acts on an object moving in air, which is determined by the object's velocity squared and the shape of the object.
When an object moves through the air, it experiences a force that opposes its motion. This force, known as air resistance, is proportional to the velocity of the object squared, meaning that a faster-moving object experiences a greater resistance. Air resistance also depends on the shape of the object, as different shapes can affect how much air flows around it and how efficiently it dissipates energy.
Air resistance is an important consideration in many fields, including aeronautics, athletics, and automotive engineering. In aeronautics, air resistance affects the performance of aircraft, and engineers must consider how to minimize it to ensure that aircraft can fly efficiently and safely. In athletics, runners also experience air resistance when they run, and it can affect their speed and performance. Finally, in automotive engineering, air resistance is a factor in vehicle drag, which can affect fuel efficiency and range.
总之,空气阻力是物体在空气中运动时所受到的一种阻力,它与物体的速度的平方和物体的形状有关。在许多领域中,包括航空、田径和汽车工程,空气阻力都是一个重要的考虑因素。
“air resistance”在英文中通常被翻译为“空气阻力”。
在一段最近的英文范文里,可能会看到这样的表述:“The aircraft encountered air resistance as it tried to take off in heavy weather.”(当飞机在恶劣天气下试图起飞时,它遇到了空气阻力。)
