平抛运动是物体以一定的水平速度抛出,只受重力作用的曲线运动.从运动性质看,平抛运动是加速度a=g的匀变速曲线运动,运动轨迹是抛物线.学习
The flat throwing motion is a curve motion where the object is thrown at a certain horizontal speed and is only affected by gravity. From the nature of the motion, the flat throwing motion is a uniform variable speed curve motion with acceleration a=g, and the motion trajectory is a parabola.
