Buoyant Force

Displacement means

• to take place

• to replace

• to fill up space

• to move aside

The relationship between area and pressure

• As area increases, the pressure increases

• As area increases, the pressure decreases.

• As area decreases, the pressure decreases

• They have no effect on each other

If an object displaces less water than its weight, the object will

• float

• accelerate

• create friction

• sink

If an object displaces more water than its weight, the object will

• float

• accelerate

• creat friction

• sink

The weight of the water displaced equals the upward force of water on an objec

• pressure

• inertia

• Archimedes' Principle

• The law of water

Pressure=

• force/volume

• volume/area

• mass/volume

• force/area

Hydraulic systems rely on all of the following except

• the incompressibility of liquids

• equal force distribution through the liquid

• output force determined by piston area

• ability of liquid to change states

fluids have the ability to

• conpresse

• freeze

• flow

• inhibit molecular motion

An object weighs 500 N. It displaces 150 N of water. While in water, the object's weight is

• 500N

• 650N

• 250N

• 350N

Why does a steel ship float, while a block of the same steel sinks?

• shape of object

• air is lighter than water

• the block's buoyancy is less than its weight

• all off the above
