Question

Define center of gravity?.........​

Answer 1

Answer:

a point from which the weight of a body or system may be considered to act. In uniform gravity it is the same as the centre of mass.

OR

Centre of gravity, in physics, an imaginary point in a body of matter where, for convenience in certain calculations, the total weight of the body may be thought to be concentrated. The concept is sometimes useful in designing static structures (e.g., buildings and bridges) or in predicting the behaviour of a moving body when it is acted on by gravity.

Answer 2

The center of gravity is a geometric property of any object. The center of gravity is the average location of the weight of an object. ... If the object is confined to rotate about some other point, like a hinge, we can still describe its motion.
