Floating and Sinking

Buoyancy is the ability to

• Sink

• Float

Positive buoyancy (stronger than object's weight) means an object will

• sink

• float

Negative buoyancy (object's weight is stronger) means an object will

• sink

• float

Density is the amount of ________ per unit of volume

• gravity

• mass

• motion

Buoyant force acts in the ________________ of gravity, making things feel lighter

• same direction

• opposite direction

Archimedes' Principal states that the buoyant force of an object is equal to the weight of the fluid it displaces.

• True

• False

1.00g/cm3 is the density of ___________________.

• vegetable oil

• honey

• water

• orange juice
