Newton`s First Law of Motion
... Newton’s first law is often called the law of inertia. Every object continues in its state of rest, or of motion in a straight line at a constant speed, unless it is compelled to change that state by forces exerted upon it. ...

... When the force of gravity acts on a body, it acts through the centre of gravity and always moves towards the centre of the earth. Symmetrical objects like balls and cubes have their CoG in the exact centre of the object. Objects are 3 dimensional, so the CoG will be at the point where the axes of al ...
