我们已经知道，速率是位移随时间的改变量，而加速度是速率随时间的改变量，则在s-t图像 (displacement- time graph)上，图像的斜率即为速率velocity;在v-t图像 (velocity- timegraph)上，图像的斜率即为加速度acceleration。而对于函数图像我们知道求斜率就是求微分，而求面积就是求积分，所以在vt图上求图像与横轴...

Speeding up and slowing down Meaning of the slope In a time vs velocity graph the slope of the line = the acceleration of the object. Analyze and calculate the motion of each stage of movement in this graph. answers First stage is +40m/s/s Second stage is +20m/s/s Third stage is ...
the instantaneous velocity is the velocity of an object under the motion in a point of time. the si unit to represent the instantaneous velocity is m/s. the instantaneous velocity can also be determined by taking the slope of the distance-time graph. free online calculators decimal to fraction...
Be able to obtain the instantaneous speed at any particular instant from a curving distance-time graph. 6. Acceleration is defined to be a = Δv/Δt. Another useful formula is v = vo + at. Remember that an object starting from rest (vo = 0) and moving with constant acceleration, trav...
moving with a uniformvelocity, the graph's slope is always straight. In simpler words, the slope of a straight line of distance-time graph represents that an object moves with a uniform velocity.Distance time graphuniform velocity is a framework of a distance traveled by a body against time....
