The center of gravity is the point in an object where its weight is evenly distributed in all directions. This means that if you were to balance the object on a single point, it would remain stable. For example, in a symmetrical object like a cube, the center of gravity is located at its geometric center. In more complex shapes, like a human body or a bicycle, the center of gravity can shift based on posture or load. Understanding the center of gravity is essential in fields like engineering, sports, and physics, as it affects balance and stability.
