What is defined as the average location of weight in an object?

The average location of weight in an object is defined as the center of gravity. This concept refers to the point at which an object's weight is evenly distributed in all directions. When an object is in a gravitational field, the center of gravity corresponds with the center of mass if the gravitational field is uniform.

In practical terms, the center of gravity is crucial for understanding how an object will behave when subjected to forces, including how it may tip or balance. For example, if you were to support an object at its center of gravity, it would remain balanced, while supporting it at any other point could cause it to tip over.

The center of mass, while similar in many contexts, is specifically about the distribution of mass rather than weight, which can differ if gravitational forces are not uniform. The equilibrium point generally refers to a position where the forces acting on an object are balanced, and the fulcrum point is the pivot around which a lever rotates. Neither the equilibrium point nor the fulcrum point address the average location of weight as directly as the center of gravity does.
