100
This is the mathematical formula for pressure.
What is F/A?
100
Things float in water when their density is less than this.
What is he density of water?
100

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

100
This principle describes how airplanes fly.
What is Bernoulli's principle?
100

The quantity defined as the product of the fluid's velocity and the cross-sectional area of flow.

What is the flow rate/continuity equation? 

200

This type of pressure results from a fluid at rest acting perpendicular to any surface.

What is hydrostatic pressure?

200
This is the density of water (in kg/m^3).
What is 1000?
200

This is how you can predict whether an object will float or sink in a fluid.

Density

200
Bernoulli's principle says that the faster that a fluid flows, the lower the __________________.
What is pressure?
200

The pressure at a depth h in a fluid of density ρ is given by this equation.

What is P = P₀ + ρgh?

300
This is the SI unit of pressure.
What is pascals?
300
This is the buoyant force on a 10kg object that has a volume of 1m^3.
What is 10,000 N?
300

This is the force that acts opposite the force of gravity and makes an object feel lighter.

buoyant force

300

Some fluids cannot be "smushed". What is the term for this?

What is incompressible?

300

This everyday weather instrument measures atmospheric pressure.

What is a barometer

400
A coffee table has a mass of 12 kg and sits on 4 legs, each with an area of 15cm^2. This is the pressure exerted on the floor by EACH leg. (Answer in N/cm^2)
What is 2 N/cm^2?
400

When an object is completely submerged, the buoyant force equals the weight of the fluid displaced, as described by this law.

What is Archimedes' Principle?

400

This is obtained when density is multiplied by the volume occupied by an object.

What is mass?

400
Pascal's principle says that F1/A1 = this.
What is F2/A2?
400

Warm air rises to sit above cold air. Why?

 Warmer fluids are less dense and rise.

500
This is the ABSOLUTE pressure experienced by a diver who is 10m below the surface of the ocean. (Use g=10m/s^2, answer in kPa)
What is 201.3 kPa? (201 kPa is also acceptable)
500

The force that opposes the weight of an object submerged in a fluid is called this.

What is buoyant force?

500

This is the ability to float in a fluid.

buoyancy

500

This term in Bernoulli’s equation represents the kinetic energy per unit volume.

What is ½ρv²?

500

The flow rate (volume/time) is represented by this equation.

What is the continuity equation? A1v1 = A2v2
