Usually when we talk about a simple object, we always use a point. The reason behind this is that we want to express an object in the simplest way possible. And there is nothing more simple than a point.

     
    Basically, the reason why we want to define all these points is because we want to gather information about the present. Those information will give us an understanding about the present situation of an object in order for us to predict the future. It's amazing how we can derive all these relationships by just starting at one point.

    We want to know if it was moving or not. We will be able to predict what will happen after some time. In short, we want to know what will happen in the future given the present situation. And that is exactly the point of using he "POINT"
