运动物体

与 运动物体 相关的网络例句 [注:此内容来源于网络,仅供参考]

When an object moves on a moving object, it is subject to a force known as Coriolis Force.

当一个物体在另一个转动的物体上运动时,这个物体似乎受到了一个力的作用,它就是科里奥利力。

Drag: a force applied by a fluid on a solid object in the opposite direction to its velocity.

拖拽力:这种力经常发生在一个固态的物体在液态物体中运动时。所受到的和它运动方向相反的力。

Classical mechanics, but Galileo, the creator of "the embryo form of law of inertia",with the incline experiment only attested to the falsity of Aristotle's proposition that "the force is the indispensable factor to maintain object movement", and not proposed what is the indispensable factor to maintain object movement.

牛顿第一定律被认为是经典力学的最基本定律之一,但"惯性定律雏型"的原创者伽利略用斜面实验只证伪亚里士多德的"力是维持物体运动不可缺少的因素"这一命题,并没有提出什么才是维持物体运动不可缺少的因素。

Objects in the thermal motion of molecules in a measure of average energy, it belongs to the molecular thermal motion of objects within the equilibrium molecular kinetic energy of the average statistics.

物体内分子的热运动平均能量的度量,它属于物体内的分子热运动平衡状态下分子动能的平均统计值。

If many forces are acting simultaneously in different directions on any body, the direction of its motion will not correspond with any one of the forces, but will always follow a middle course, the summary of them, what is expressed in mechanics by the diagonal of the parallelogram of forces.

如果同时有许多各种不相同的力作用于某一物体,该物体运动的方向不可能与任何一个力的运动的方向相符合;而总是平均最短的方向,即力学所说的平行四边形的对角线。

It is also a familiar fact that a force is rettulred to slow down or stop a body which is already in motion, and that a sidewise force must be exerted on a moving body to deviate it from a straight line.

要使一个已经运动的物体慢下来或使其停止运动就需要作用力;要使该物体偏离直线运动,就需要横向作用力,这也是大家所熟悉的事实。

Sliding friction contact with each other objects to impede the relative movement between the force is not necessarily impede the movement of objects.

滑动摩擦相互接触其他物体阻碍之间有相对运动的力量,并不一定阻碍物体的运动。

An object at rest tends to stay at rest and an object in motion tends to stay in motion with the same speed and in the same direction unless acted upon by an unbalanced force .

一节运动的物体趋向于仍保持原来的速度的大小和方向运动,静止的物体将永远静止,除非有不平衡的外力迫使它改变这种状态为止。

When infrared ray irradiates to the surface of material and radiating frequency is same as material molecular frequency, the radiating energy is strongly absorbed by the material.

红外辐射是辐射物体以电磁波的方式传播内能的过程,当红外线照射到某一物体时,如果入射的红外线频率和物体分子固有频率相一致,则物质分子就会表现出对红外线的强烈吸收,吸收的那一部分能量就转化为分子的热运动,使物体温度升高,达到加热干燥的目的。

Based on the principle of special relativity, the formula of "Light Pressure" and the equation of movement of the object propelled by photon propulsion under the condition of movimg object are deduced.

利用狭义相对论推导了物体运动情形下的光压公式和光子推进下物体的运动方程,分析了光子推进过程中的能量转换关系。
