buoyancy

Buoyancy refers to how much an object can float or rise in water. It's also about feeling light and free, like when you're walking on air.

When people talk about buoyancy, they usually mean it in a physical sense - like how a boat floats on the surface of the ocean because it's less dense than the surrounding water. You might hear a physicist explain that the shape of an object affects its buoyancy, making some things more likely to float than others. In everyday life, people often use the word when talking about inflatables or pool toys that provide extra support in the water.
