Find out what buoyancy is and why things sink or float with a Bitesize 2nd level Science Explainer.
Buoyancy depends on volume and so an object's buoyancy reduces if it is compressed and increases if it expands. If an object at equilibrium has a compressibility less than that of the surrounding fluid, the object's equilibrium is stable and it remains at rest.
Oct 18, 2024 · When an object is immersed in a fluid, wholly or partially, the fluid exerts an upward force opposite its weight. This phenomenon is known as buoyancy, and the upward thrust is known as the buoyant force. A characteristic of buoyancy is that it determines whether an object will float or sink. Buoyancy.
4 days ago · Buoyancy determines how objects behave in liquids and gases. It aids ships sailing oceans, balloons soaring in the sky, and marine life inhabiting different depths. Definition of Buoyancy. Buoyancy is defined as the force exerted by a fluid that opposes the weight of an object immersed in it. This force enables objects to float.
Sep 16, 2024 · Archimedes’ principle, physical law of buoyancy stating that any body submerged in fluid (gas or liquid) at rest is acted upon by an upward, or buoyant, force, the magnitude of which is equal to the weight of the fluid displaced by the body.

Archimedes’ principle refers to the force of buoyancy that results when a body is submerged in a fluid, whether partially or wholly. The force that provides the pressure of a fluid acts on a body perpendicular to the surface of the body.
The net upwards force from the pressure of the fluid must remain the same, \(F_{B}\), but that force is now exerted on the hull of the boat. We call that force the force of “buoyancy”, which is the reason that a boat can float and the reason that you feel lighter when walking in a swimming pool than on land.
