抛物运动指物体以一定的初速度抛出后,在地面附近不大的范围内仅在重力作用下的运动.依据运动的独立性和等时性,运动学中常将较为复杂的曲线运动分解为某两个方向的直线运动.分解思路一抛物运动仅受重力,抛物运动最常见的分解方法分解为水平方向的匀速直线运动和竖直方向a=g的匀变速直线运动. Parabolic motion refers to the object under a certain initial velocity thrown out, not in a large area near the ground only under the action of gravity.According to the independence of motion and isochronism, kinematics often more complex curve movement is decomposed into Decomposition ideas A parabolic movement is only gravity, parabolic decomposition of the most common method of decomposition into a horizontal direction of the uniform linear motion and vertical direction a = g uniform linear motion.
