center of gravity: meaning, definition, pronunciation and examples

In most practical contexts on Earth, yes. Technically, 'center of mass' is the average position of all mass, while 'center of gravity' is the average location of weight, which is affected by gravity's uniformity. In non-uniform gravitational fields, they differ.

Yes, it is very commonly used metaphorically. For example, 'The center of gravity in the film industry has moved towards streaming services.' It means the main focus, power, or influence has shifted.

For simple, symmetrical objects, it's at the geometric centre. For complex objects, it can be found experimentally by suspending it from different points; the center of gravity lies where the plumb lines from these suspension points intersect.

A low center of gravity makes an object more stable and less likely to tip over because less force is required to keep its mass balanced over its base. This is why sports cars and heavy furniture are designed with a low center of gravity.

The point in an object or system where its mass can be considered to be concentrated and about which it balances.

Center of gravity is usually technical, academic, metaphorical in register.
