一、平抛运动的求解方法1.常规解法是运动的分解(1)水平方向和竖直方向的两个分运动是相互独立的,其中每个分运动都不会因另一分运动的存在而受到影响.(2)水平方向和竖直方向的两个分运动及其合运动具有等时性.由t=(2h/g~(1/2))可知,平抛物体在空中运动的时间t只决定于物体抛出时离地的高度h,而与抛出时的初速度v_o无关.
First, the method of solving the plane throwing motion 1. The conventional solution is the decomposition of the motion (1) The two sub-movements in the horizontal direction and the vertical direction are independent of each other, and each sub-movement is not due to the existence of another sub-movement. (2) The two sub-movements in the horizontal and vertical directions and their joint movements are isochronous. From t=(2h/g~(1/2)) we can see that the parabolic objects move in the air. The time t is only determined by the height h from the ground when the object is thrown, and is independent of the initial velocity v_o at the time of throwing.
