1一种思想:按实际需要分解运动平抛运动是中学阶段重要过程模型:匀变速曲线运动.它帮助我们理解运动的合成与分解,一般我们把它理解为水平匀速直线运动和竖直方向的自由落体运动.不过,在一些问题中我们不能只拘泥于这种分解,如果充分利用分解思想,灵活的分解,会使问题的解决变得更明朗、简洁.
1. An idea: Decomposing the motion flattering motion according to actual needs is an important process model in middle school: uniform variable curve motion. It helps us to understand the synthesis and decomposition of motion. Generally, we understand it as horizontal uniform linear motion and vertical direction. Free fall movement. However, in some problems we cannot just stick to this decomposition. If we make full use of decomposition ideas and flexible decomposition, the problem will be resolved more clearly and concisely.
