运动物体通过的路径叫做物体的运动轨迹。运动轨迹是一条直线的运动,叫做直线运动。
匀加速 直线运动 ( rectilinear motion )是一维的匀加速运动,质点的轨迹沿一条直线。若将轨迹取为 轴,则速度和位置与时间的关系式是:

假设有一物体,沿直线运动,我们把它称为一维运动。
I have a motion of an object along a straight line we'll call that one-dimensional motion.
当然,如果是做直线运动,这两种概念是一样的。
Of course, if you are moving in a straight line, then the two notions are the same.
现在来假设物体加速度,其总量取决于物体,与直线运动速度的偏差。
And suppose you postulate that the acceleration of the body, that is the amount it deviates from the straight line motion that it would otherwise take.
One way to say it is, every body will continue to remain in a state of rest or uniform motion in a straight line.
另外一种说法是,任何物体都会继续保持静止,或匀速直线运动的状态
