一、竖直上抛运动的特征把物体以某一初速度竖直向上抛出，在忽略空气阻力的情况下物体所做的运动叫竖直上抛运动，可见上抛运动的特征是：（1）初速度v0竖直向上，（2）加速度恒为重力加速度g，（3）具有往返性。所以上抛运动是初速度为v0、加速度为g的匀变速直线运动。由于竖 First, the characteristics of the vertical throwing movement throws the object vertically upwards at a certain initial speed. In the case of ignoring the air resistance, the movement of the object is called vertical throwing movement. The characteristics of the upward throwing movement are: 1) The initial velocity v0 is vertically upwards, (2) the acceleration is constant as the gravitational acceleration g, and (3) has reciprocity. So the throwing motion is a uniform speed linear motion with initial velocity v0 and acceleration g. Due to vertical
