Pressure
pressure
This is obtained when density is multiplied by the volume occupied by an object
mass
state the type of fluid used in

Fluid is a ....
any substance that flows and is a state of matter.
Anything that has mass and volume is considered...
matter
what factors affect pressure
temperature, volume, number of particles
This is the force that acts opposite the force of gravity and makes an object feel lighter
buoyant force
jaws of life that rescue workers use are an example of what..
hydraulic systems
fluids are
gases and liquids
All matter is made up of tiny particles
What is one of the postulates?
Air pressure can be measured with this device
barometer
According to ........ principle the buoyant force on an object is equal to ......... displaced by the object
the Archimedes' principle
the weight of the fluid displaced
When a force is applied to an enclosed fluid, the increase in pressure is transmitted equally to all parts of the fluid.
Pascal's Principle/Law

chaotic changes in pressure and velocity
Mass is ....
A measure of how much matter is in a substance
How does compression affect pressure
As the volume of a container decreases, the pressure increases
will tell you if a object will sink or float

Turbulent flow
An increase in the volume of a substance in response to an increase in its temperature is
Thermal expansion
What happens to atmospheric pressure as elevation increases and this is what happens to water pressure as depth increases?
decreases and increases
This is an example of a device that moves fluid by increasing the pressure on the fluid
medicine dropper
air pump
it is a disk that moves inside a cylinder
piston
smooth and regular describes what flow
Laminar flow
