What is the equation for pressure
pressure = force/area
What is the apparent loss of weight of objects when submerged in a liquid
Buoyancy
An object's _________ determines its buoyant force.
Volume
The principle of flotation states that a floating object displaces a weight of fluid equal to its own _______.
Weight
How much a liquid weighs and how much pressure it exerts depends on its ___________.
Density
________ _______ is an upward force that water exerts that is opposite in direction to gravity.
Buoyant force
When an object's buoyant force equals the weight of the completely submerged object, then the object's weight must _____ the weight of the displaced object.
Equal
Suppose you sink a bowl in water. When the weight of the displaced water _____ the weight of the bowl, it will sink no more.
Equals
What is the equation for pressure due to liquid
weight density x depth
A completely submerged object always displaces a volume of liquid _______ to its own.
equal
An object _____ deanse than the fluid it is immersed in sinks
More
True or false.
Pascal's principle applies to both gases and liquids.
True
An object has a force of 25N and an area of 0.046m^2. What is the object's pressure?
540Pa
True or False
Is Archimedes principal true for liquids, gases, and solids?
False, Archimedes principle is only true for liquids and gases
An object ______ dense than the sluid it is immersed in floats
Less
__________ principle states that changes in pressure at any point in an enclosed fluid at rest are transmitted undiminished to all points in the fluid and act in all directions.
Pascal's Principle
An object with a weight density of 50kg/m^2 and a depth of 32m. What is its pressure?
1600Pa
What is the principle that states that "an immersed object is buoyed up by a force equal to the weight of fluid it displaces."
Archimedes Principle
An object with density _____ to the density of the fluid it is immersed in neither _______ nor ________
equal, sinks, floats
If you immerse a bowl into water, what will happen if you continue to immerse the bowl into the water?
More water will be displaced, and the bowl will have a greater buoyant force.
