1.图1表示一个沿水平面运动的物体的多次闪光照片,闪光时间等间隔分开。物体开始运动时第一次闪光到静止时最后一次闪光。 2.某物体速度与时间的函数关系如图4所示,以下哪张图(图5)最好地代表了物体的合力与时间的关系。
1. Figure 1 shows multiple flash photos of an object moving along a horizontal plane with flashing time separated by equal intervals. The first flash when the object started to move to the last flash at rest. 2. The relationship between speed and time of an object As shown in Figure 4, which of the following diagrams (Figure 5) best represents the relationship between the resultant force of an object and time.
