What is the name of the device that lifts or drops a tractors bucket. It has a hose with hydraulic fluid going into it.
A ram
A hydraulic jack uses his principle.
Pascal's
The Unit that is used to measure pressure.

How could you decrease the density of a round ball of clay?
Flatten it out so it takes up more volume.
The force that opposes motion in a fluid is ...
Drag
Hydraulics use a liquid because liquids do not ______ easily.
Compress
If the speed of a fluid is increased, the pressure exerted by the fluid decreases.
Bernoulli's
Why aren't we smashed like a bug by the air pressure that is on us?
We have air pressure pushing out of us.
If you increase the volume of a substance, what happens to its density?
It decreases
The upward force on a wing is known as ...
Lift
Whose principle uses hydraulics?
Pascal's
An airplane's wings create lift because of this principle.
Bernoulli's
As we go up in elevation, what happens to air pressure?
Air pressure decreases
Why can a large steel ship float on water?
It has a very large buoyant force and it a low density because it has such a large volume.
What are the 4 forces of flight?
Thrust, Drag, weight (gravity), lift
A change in pressure at any point in an enclosed fluid will be transmitted _____ to all parts of the fluid.
equally
A large steel ship floats because a large amount of water is displaced.
Archimedes
