It is the force working upwards if it is greater in value than to the gravity force of the floating object that works downwards.
if it was less then call it negative buoancy and then the floating object will tend to be unstable (subject to sink)
Three types of buoyancy are positive buoyancy, negative buoyancy, and neutral buoyancy. Positive buoyancy occurs when an object is lighter than the fluid it displaces, causing it to float. Negative buoyancy happens when an object is heavier than the fluid it displaces, causing it to sink. Neutral buoyancy is when an object has the same density as the fluid it displaces, resulting in it neither sinking nor floating.
The two main types of buoyancy are positive buoyancy, which causes an object to float, and negative buoyancy, which causes an object to sink. Another type, neutral buoyancy, occurs when an object neither sinks nor floats but remains suspended in water at a specific depth.
If you float well the buoyancy is positive (your mass is less than the mass of the displaced liquid (water?), if you just manage to float or at least don't sink at any great speed, the buoyancy is neutral (your mass equals the mass of the liquid displaced).
Negative buoyancy is when an object weighs more than the weight of the fluid it displaces, causing it to sink. In the case of a blimp, negative buoyancy can prevent it from floating in the air and instead cause it to descend. This can be counteracted by adjusting the blimp's ballast or level of helium to achieve neutral or positive buoyancy.
We are merely testing the buoyancy of several types of ping pong balls.
You can determine your buoyancy by observing whether you float, sink, or stay suspended in water. If you float on the water's surface, you have positive buoyancy. If you sink, you have negative buoyancy. When you remain suspended at a certain depth, your buoyancy is neutral.

Positive Buoyancy. When submarine submerges, it initially uses negative buoyancy to submerge, and then levels out to neutral buoyancy.
An object has positive buoyancy when it weighs less than the fluid it displaces. This causes the object to float in the fluid, as the buoyant force pushing upward is greater than the force of gravity pulling downward. Objects with positive buoyancy will naturally rise to the surface of a fluid.

By having positive buoyancy.

A submarine has a variable buoyancy due to it's ballast tanks. When a submarine submerges, it fills it's ballast tanks with water which causes negative buoyancy. When a submarine surfaces, it pumps the water out of the ballast tanks thus giving it positive buoyancy.
Positive buoyancy . . .When the object is completely submerged, the net force on it ... the combinationof gravity down and buoyancy up ... is upward, so the object tries to rise.Negative buoyancy . . .When the object is completely submerged, the net force on it ... the combinationof gravity down and buoyancy up ... is downward, so the object tries to sink.Neutral buoyancy . . .When the object is completely submerged, the net force on it ... the combinationof gravity down and buoyancy up ... is zero. The object stays at whatever depthit is released, without rising or sinking.
If a body is floating IN a liquid, it has neutral buoyancy- does not go up or down. If it is floating ON a liquid, it has positive buoyancy. Neutral- when pressed down, body moves down- and when released, it stays there. Positive buoyancy- moves down, when released returns to it's position on top of the liquid.
Negative buoyancy is when an object weighs more than the weight of the fluid it displaces, causing it to sink. In the case of a blimp, negative buoyancy can prevent it from floating in the air and instead cause it to descend. This can be counteracted by adjusting the blimp's ballast or level of helium to achieve neutral or positive buoyancy.
