What a waste of time, we all know in order to get that ball moving we all have to push together. It would nearly impossible to move that ball even if that sphere is hallow.
Even when they all push together is still going to be difficult task. As Galilee put it the greater the inertia of an object the harder it is to get it to move, by the way another name for inertia is mass.
In this section we will examine the Newton's three laws of motion and how it can change the motion of an object.
