结合高考题和模拟题分析了速度一位秽图象斜率的含义,指出只有初速度为0的匀加速直线运动,其速度一位移图象的斜率才等于时间的倒数,所有的速度一位移图象的斜率都等于瞬时加速度与同一时刻瞬时速度的比值,并讨论能否利用v-x图象求时间。
This paper analyzes the meaning of the slope of a dirty image in the velocity field and points out that only the slope of the velocity-displacement image equals the reciprocal of the time if only the uniform acceleration linear motion with the initial velocity is 0. All the velocity- The slope of the image is equal to the ratio of the instantaneous acceleration to the instantaneous speed at the same moment and discusses whether the vx image can be used to find the time.
