Which action will increase an object's buoyancy?

Increasing an object's buoyancy can be achieved by increasing its displacement. Buoyancy is the upward force that a fluid exerts on an object submerged in it, and this force is influenced by the volume of fluid displaced by the object. According to Archimedes' principle, the buoyant force is equal to the weight of the fluid that the object displaces.

When you increase an object's displacement, you effectively increase the volume of water or fluid it pushes aside. This leads to a greater buoyant force acting on the object, which can help it float more easily or rise in the water column. For diving and swimming, understanding how to manipulate buoyancy is crucial for safety and stability underwater.

Adding weight decreases buoyancy, while reducing weight can potentially increase buoyancy, but both actions do not directly enhance the object's capacity to displace more fluid beyond its existing volume. Decreasing displacement would similarly diminish buoyancy because less fluid would be displaced, leading to a reduced buoyant force. Thus, increasing the displacement is the most effective way to enhance buoyancy.
