运动学研究的是质点的空间位置随时间变化的规律,它不涉及运动的条件.重点是匀变速直线运动的规律,以及运动的合成与分解.虽说解答这类问题,有许多现成的公式,但同学们若善用运动的性质,不仅能找到突破题目难点.缺口,而且还能使某些习题解答简捷而不落俗套,巧妙而富有新意.下面举例说明“运动”的几种常见性质的运用. Kinematics studies the law of the location of particles in space over time. It does not involve the conditions of movement. The emphasis is on the law of uniform linear motion, and on the synthesis and decomposition of motion. Although there are many formulas available to answer such questions, However, if students make good use of the nature of sports, not only can they find breakthroughs and difficult points, but they can also make certain exercises answer simple, unconventional, clever and innovative. Here are some examples of the common nature of “sports”. use.
