Center of Gravity
Center of gravity is often called the “Center of Mass” and is defined as the point at which all mass seems be concentrated.
Center of Gravity is a balance point.
You can use a plumb bob to find the center of gravity

Toppling
When an object’s center of gravity is over its base it will remain upright, however if the center of gravity extends beyond the base it will topple.
