平抛运动的特征(1)平抛运动是一种匀变速曲线运动,加速度α=g,方竖直向下;初速度v0的方向与竖直方向垂直,但其他任一时刻的合速度的大小方向都在发生变化。(平2)抛平运抛动运可动以规分律解为两个分运动:①水平方向上初速度为v0的匀速直线运动;②竖直方向上的自由落体运动。如 Characteristics of flat-throw motion (1) Flat-throw motion is a uniform variable-speed curve motion, acceleration α = g, square vertical downwards; initial velocity v0 is perpendicular to the vertical direction, but at any other time The size direction is changing. (Flat 2) The throwing transport can be moved to regulate the law to be divided into two sub-movements: 1 The horizontal velocity is a uniform linear motion with an initial velocity of v0; 2 The free-fall motion in the vertical direction.
