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, a seesaw has its center of gravity at the midpoint, allowing it to balance when equal weights are placed on either side. In everyday objects, the center of gravity can change based on their shape and how mass is distributed. For instance, a bicycle has a lower center of gravity when a rider is seated, making it more stable compared to when the rider stands up.
