平抛运动是一类重要的匀变速曲线运动,它的特点是物体以一定的初速度水平抛出,只受重力作用.在实际中,我们还常常遇到所谓类平抛运动.只要满足以下两个条件,物体的运动就属于类平抛运动:1.物体受恒力作用;2.初速度方向与恒力垂直.
Flat throwing motion is an important type of uniform variable speed curve motion. Its characteristic is that the object is thrown at a certain initial velocity level and is only affected by gravity. In reality, we often encounter so-called flat throwing motions. As long as the following is satisfied In both conditions, the motion of the object belongs to the category of flat-throwing motion: 1. The object is subjected to a constant force; 2. The direction of the initial velocity is perpendicular to the constant force.
