What is the center of gravity defined as?

The center of gravity is correctly defined as the point at which the weight of a body is concentrated. This means that if you were to suspend the body at this point, it would remain in equilibrium without tipping over. It is a critical concept in physics and biomechanics because understanding the center of gravity helps in predicting how an object will behave when subjected to forces such as movement or external loading.

The center of gravity varies depending on the shape and mass distribution of an object. For example, in a symmetrical shape, the center of gravity is typically located at the geometric center, whereas in irregular shapes, it may be offset from the center. This concept is vital for areas such as assistive technology and rehabilitation, where precise balance and control are needed for mobility devices and prosthetics.

The other options describe related but distinct concepts. The physical strength of the body is not relevant to the definition of center of gravity, as it does not pertain to the balance or weight distribution. The location of balance via external forces is more about stability rather than the intrinsic properties of the body itself. Lastly, the measurement of a body’s mass distribution refers to how mass is spread out within the body, but it does not equate to the specific point of concentration of that mass
