uniform motion 【機械工程】勻速運動。

uniform system

The newton the first laws finger object is had the character keeping original motion state , the inertia theorem is also called : under the circumstances of not accepting an outside force or being accepted an outside force by zero , the object always keeps uniform motion or motionless 牛頓第一定律指物體具有保持原來運動狀態的性質,也被稱為慣性定理:在不受外力或所受外力為零的狀態下,物體總保持勻速運動或靜止。

When lorentz symmetry holds , spacetime is isotropic in the sense that all directions and all uniform motions are equivalent , so none are singled out as being special 當勞侖茲對稱成立時,時空是具有等向性的,也就是所有方向與所有等速運動皆等效,沒有一個是特別的。

Every body continues in its state of rest , or of uniform motion in a right line , unless it is compelled to change that state by forces impressed upon it 如果物體處于靜止狀態或作勻速直線運動,只要沒有外力作用,物體將保持靜止狀態或勻速直線運動狀態。

An object at rest or traveling in uniform motion will remain at rest or traveling in uniform motion unless acted upon by a net force 所有物體在沒有受到力的作用的時分,總堅持靜止狀態或勻速直線活動狀態。

If you were content to remain at rest or in uniform motion relative to an unaccelerated frame of reference, no force would be needed . 如果你愿意相對于一個非加速的參照系去保持靜止或勻速運動,并不需要有力作用。
