buoyancy

(1) The degree to which a body floats in a liquid.
(2) The force exerted by a fluid on a floating body, which opposes the force of gravity and is equal to the  body’s density.

At high enough spin speeds with a polymer with low enough viscosity, buoyant forces aid in removing bubbles.
Considering olive fruits in water, the forces acting on the sample will be the gravitational force (Fg) acting downward, buoyant force (Fb) acting upward, and drag force (Fd) acting opposite to the direction of motion.
Things weigh less in water because of the buoyant force pushing up on them.
problem of comparing the magnitude of buoyant force on two objects:
Because helium is about seven times less dense than air, it provided enough buoyant force (upward force on an object immersed In air or liquid) for the balloon cluster to rise.
With a squashed bubble, the volume of air in the diver is less, so the buoyant force on the diver is less.
This provides the buoyant force (upward force on an object immersed in a gas or liquid) needed for the balloon to float.
On race day, the sponsored ducks get released into Dyes Inlet The upward, buoyant force of the water keeps the lightweight ducks afloat as they glide on the water's surface along a marked route.
Every cubic meter of helium in balloons gives enough buoyant force (upward force on an object immersed in air or liquid) to lift 1 kilogram (2.
12) that one cubic meter of helium has enough buoyant force to lift about 1 kilogram (2.
The buoyant force of helium can lift about one gram per liter of the gas.
