The tendency or ability of an object to float.
Buoyancy The tendency or ability of an object to float.

Buoyancy The pressure on the bottom of a submerged object is greater than the pressure on the top. The result is a net force in the upward direction.

Buoyant Force The upward force exerted by a fluid on a submerged or floating object.

Buoyancy The buoyant force works opposite the weight of an object.

Density and buoyancy: An object that has a greater density than the fluid it is in, will sink. If its density is less than the fluid it will float. Density

To find the volume of the prism use the formula V = lwh
3cm To find the volume of the prism use the formula V = lwh where V is volume, l is length, w is width, and h is height h w l V = lwh V = (3)(3)(3) V = 27 cm^3

Density Changes in density cause a submarine to dive, rise, or float. This is called a Ballast Tank
