A car is exerting 15 Newtons down on a 5 m^2 area. What is the pressure of that object?
3 Pa
100
If the pressure of an object is 5 Pa and the area of it is 10 m^2. What is the Force of that object?
50 N
100
In a hydraulic system what is the name of the machine that pushes the fluid?
(Hint: Starts with a P)
A piston
100
What generates thrust in a plane
What is motor
100
What is roll
plain tilts to left or right
200
What part of an object experiences the most pressure in a submerged object
The bottom because that part is deeper although it is the same fluid.
200
The higher an object goes up in the atmosphere, the _______ the pressure gets
lower
200
If a full small piston pushes all of its fluid to a larger piston? Will it fill the larger piston?
No.
200
Why does the wing generate lift
The wings pushes air down and then an equal and opposite force pushes it up
200
Water pressure increases as depth _____?
increases
300
What does the object do if the buoyant force pushing it up is equal to the weight of the object pushing it down
It is suspended
300
A change in pressure in a fluid is transmitted where.
All directions
300
What fluid do most modern machines use for their pistons?
Oil
300
What does the elevator
It pitches (a strike)!!!!
300
An object sinks when...?
the weight of an object is greater than the buoyant force pushing it up?
400
Why can a steel ship float?
The weight of the steel is less than the weight of the water it is displacing.

Why does a ping pong ball hovers in air above a hair drier?
The hair drier creates air flow with lower pressure than the air surrounding it, and the ping pong ball stays in the low pressure air.
400
Why do the small pistons usually come before larger pistons?
We want more force out of it. If it was the other way around there would be more distance.

What is the body of the plain called?
fuselage
400
What does the flap and spoiler create in planes?
drag
500
If the force of an object is 25 N and the Area is 50,000 cm^2. What is the pressure in pascals?
125 Pa

In a hydraulic system, the small piston's area is 3 m^2 and the big piston's area is 15 m^2. If the input force on the small piston is 5 N what is the big piston's output force?
