It's something I throw up has an initial speed of 10 meters per second.
抛出物体的,初速度是10米/秒
So,the point is,every object falling under gravity is given by the same formula, but there are many, many objects that can have many histories, all falling under gravity, and what's different from one object and the other object is, when was it dropped, from what height, and with what initial speed.
关键是,每一个受重力作用下落的物体,都有同样的表达式,但是各个受重力作用下落的物体,都有不同的初始条件,所以它们的区别在于,下落时刻,下落高度和初始速度
Car is traveling with some initial speed v0 in the horizontal direction.
车以 v0 的初速度沿水平方向开出
