通过设置特殊的环境,使物体的运动在圆周轨道与平抛轨道之间改变,借此可以考查圆周运动、平抛运动及功能知识、电磁场知识.本期先讨论在重力场环境中物体的变轨.在竖直平面内,通过直线运动、平抛运动、圆周运动轨迹的衔接,设置运动的“变轨”情景,可考查运动学知识和规律及能量守恒思想.
By setting a special environment, the movement of the object is changed between the circular orbit and the flat orbit, so that you can examine the circular movement, flatten the movement and functional knowledge, electromagnetic field knowledge.This issue first discusses the object in the gravitational field environment changes In the vertical plane, through the linear motion, flat throwing motion, the convergence of circular motion trajectory, set the motion “orbit ” scene, you can check the kinematic knowledge and laws and conservation of energy ideas.
