匀变速直线运动的一些规律在曲线运动中是否也能适用呢。本文通过对一个结论的拓展,说明对于匀变速曲线运动中间时刻的瞬时速度与整个过程中的平均速度完全相同。
Even if some laws of variable speed linear motion in the curve can exercise it. In this paper, a conclusion is extended to show that the instantaneous speed at the middle of the motion of the uniform speed-change curve is exactly the same as the average speed of the whole process.
