Center of Mass

Let us learn about center of mass,

Every object has a center of mass, which can be thought of as the point that is as close as possible to every piece of an object. Usually the center of mass is found within the object. For example, the center of mass of a ball is the very middle of the ball, and the center of mass of a book is the middle of the book. Where do you think the center of mass of your pencil is? How about the center of mass of your body? Talk about this with you mentor.

The center of mass determines whether or not something will fall over. Imagine pushing over a refrigerator. At the beginning, the center of mass is directly over where the fridge touches the ground.

If you push the refrigerator a little, it will fall back into place. If, however, you push it enough so that the center of mass is past the piece of the fridge that is touching the ground, it will fall.
