对于非匀变速直线的问题,由于其加速度是变化的,那么匀变速运动的公式在此就派不上用场了,但利用v-t图象的特点:图象的斜率表示加速度(如图图象是曲线,则曲线上某点的切线的斜率表示该点的加速度),图象与坐标轴所围成的“面积”表示物体的位移,却可以使得不能用公式求解的问题得到解决,提高解题速度,起到事半功倍的效果。 For non-uniform speed straight line problems, because of its acceleration is changing, then uniform variable speed motion here would not come in handy, but the use of vt image features: the slope of the image that acceleration (as shown in the image is Curve, the slope of a tangent at a point on the curve indicates the acceleration of the point). The “area” enclosed by the image and the coordinate axis represents the displacement of the object, but the problem that can not be solved by the formula can be solved and increased Solve the problem, play a multiplier effect.
