斜抛运动作为平抛运动的一种延伸,在日常生活中常见,对于涉及斜抛运动这类问题学生解答起来感觉比较费劲,甚至无从下手,而结合矢量三角形定则,我们不但能将问题同样解决,并且还方便、简洁和易懂.斜抛运动是以一定的初速度将物体与水平方向成一定角度斜向上抛出,物体仅在重力作用下所做的曲线运动.投出的标枪和手榴弹,大炮发射的炮弹,它们的运动都是斜抛运动.做斜抛运动的物体,先是沿着曲线上升,升
As an extension of flat throwing exercise, oblique throwing throwing exercise is common in daily life. It feels strenuous or even impossible for the students involved in such problems as oblique throwing throwing. Combined with the vector triangle rule, we can not only solve the same problem Solve, and is also convenient, concise and easy to understand.Leish throwing movement is a certain initial velocity of the object at an angle to the horizontal direction of the oblique throw, the object only under the action of gravity curve made. Javelin and Grenades, shells fired artillery shells, and their movements are oblique throwing exercise. Do oblique throwing objects, the first along the curve rise, rise
