| 摘 要： | 以物体做匀变速直线运动的判断方法,对利用位移差相等(△S=aT~2)来判断物体是否作匀变速直线运动进行分析,论证了位移差相等只是判断物体作匀变速直线运动的必要条件,给出了该判断的充要条件是△S=aT~2 V_0=(S_1-(1/2)△S/T).对验证匀变速直线运动的实验提出了采用频率可调打点计时器和对运动物体增系一个速度计等改进意见.

| Abstract: | Based on some methods about ascertaining uniformly changed velocity rectilinear motion,the analyses focused on equal displacement aberra- tion condition,the result shows that the condition is only necessary.Whether this motion is uniformly changed rectilinear motion can be ascertained by con- ditions(?),Using the adjustable frequency instrument and velocity meter is suggested in the paper in the experiment of ascertaining a motion is unifonnly changed velocity rectilinear motion or not. |
