What term refers to the point where the weight of an object is concentrated?

• A. Center of gravity
• B. Center of mass
• C. Pivot point
• D. Neutral axis

Answer: (A)

Center of gravity is the point at which the entire weight of an object can be considered to act. In a uniform gravitational field like Earth’s, all weight effectively funnels through a single location that also matches the center of mass—the average location of the object's mass. This makes the center of gravity the best term for describing where weight is concentrated, especially for analyzing stability and tipping in vehicle rescue scenarios. The center of mass describes mass distribution rather than the force of gravity itself, though they coincide under normal Earth gravity. A pivot point is about rotation about an axis, not where weight acts, and the neutral axis is a bending concept inside a cross-section, not a weight concentration point.
