两个或两个以上物体相互连接参与运动的系统称为连接体,它们存在着位移、速度和加速度等物理量的关系.教材中典型的探究牛顿第二定律实验,小车与盘及盘中重物就构成了连接体,它们的位移、速度和加速度关系明了简单.为了发展学生潜能,有人就编成了其他形式的连接 Two or more objects connected to each other to participate in the movement of the system known as the connector body, they exist displacement, velocity and acceleration and other physical quantities of the relationship between the typical textbook to explore Newton’s second law experiment, car and disk and heavy disc They form a connection, their displacement, velocity and acceleration of the relationship between the simple and clear in order to develop the potential of students, someone compiled into other forms of connection
