In26.100, we will use the air track when we start colliding objects and try to see what happens before and after the collision. 在26。100中,气垫碰撞到物体,为16。100空气动力学,然后观测碰撞,前后的效果。
You are not stuck, like you are there, to one dimension of going back and forth on what we call the air track. 不像气垫导轨那样被束缚在一维,只能来来回回移动装置。
Now I want to do more completely elastic collisions, and I'm going to do that with the air track. 我还想做更多,完全弹性碰撞,我将用空气轨实验。
Here is the air track. 这里是空气轨。
I have a demonstration set up on this air track, and we do it on an air track so there is a minimum of friction. 我在空气轨上演示,在空气轨上演示,尽量减小摩擦。
