Sea Perch Buoyancy

When an object sinks:

• The weight of the object is greater than the upward buoyant force.

• The weight of the object is less than 1g.

• The weight of the object is less than the upward buoyant force.

• The weight of the object is equivalent to one liter of water.

Archimedes said that

• the weight of the displaced liquid is equal to the buoyant force.

• the weight of the object is equal to the buoyant force.

• the buoyant force is equal to the density of the object.

• the buoyant force is equal to gravity.

An object is neutrally buoyant when

• the density of the object is equal to the liquid it is submerged in.

• it neither sinks nor floats.

• the weight of the object is equal to the buoyant force.

• All of the above.

Mass is

• weight.

• density.

• a measurement of matter.

• none of the above.

Weight is

• a measurement of matter.

• mass X gravity.

• mass.

• gravity.

Density is

• a material's ability to float.

• a material's volume per unit mass.

• a material's thickness.

• a material's mass per unit volume.

If the object's weight is greater than the upward buoyant force

• additional weight is needed to be neutrally buoyant.

• the object will float.

• additional buoyant force is needed to be neutrally buoyant.

• additional buoyant force will cause it to sink.

If the object's weight is equal to the buoyant force

• the object is neutrally buoyant.

• the object will neither sink nor float.

• the object will remain at rest.

• all of these.
