Buoyant Force Explained: Objects Floating on Fluids!

When an object floats on a fluid, what is the relationship between the buoyant force and the force of gravity acting on the object?

• The buoyant force is greater than the force of gravity.

• The buoyant force is less than the force of gravity.

• The buoyant force is equal to the force of gravity.

• The buoyant force is zero.

A wooden sphere with a density of 660 kg/m³ floats on water with a density of 1.00 x 10³ kg/m³. What percentage of the sphere's volume is submerged below the water surface?

• 34%

• 66%

• 100%

• 0%

What is specific gravity?

• The ratio of an object's mass to its volume.

• The ratio of the density of a substance to the density of a standard substance.

• The force exerted by a fluid on a submerged object.

• The percentage of an object's volume submerged in a fluid.

For a given object and fluid, which factor does NOT affect the percentage of the object's volume that is submerged when it floats?

• The density of the object.

• The density of the fluid.

• The shape of the object.

• The acceleration due to gravity.
