Problem statement

The centre of gravity of an object is the average position of the weight of an object.

The motion of an object can be completely described by the translation of the centre of
gravity, and by rotations about the centre of gravity.

When an object is static, its tendency to tip, or resist tipping, is determined by the position of the centre of gravity relative to the base upon which the object is resting.

How can you determine the position of the centre of gravity of an object?
