平抛运动是匀变速曲线运动中的常见运动,它可以看作由匀速直线运动和自由落体合成,因此也是两个直线运动合成后为曲线运动的典型例子,其基本规律和处理方法一直是各类考试的热点.下面介绍平抛运动中几个重要结论的证明及应用.结论1:平抛运动的末速度的反向延长线交平抛运动水平
Flat-throwing motion is a common motion in uniform variable-speed curve motion. It can be regarded as a combination of uniform linear motion and free fall. It is also a typical example of two linear motions combined into a curved motion. Its basic laws and processing methods are always Exam hotspots. The following describes the proof and application of several important conclusions in the plane-throwing exercise. Conclusion 1: The backward speed of the flat-throwing motion
