Pressure
Archimedes' Principle
Pascal's
Bernoulli's
100
A force exerted on a surface.
What is Pressure?
100
The ability to float.
What is buoyancy?
100

It uses a liquid to to transmit pressure in a closed system

What is a hydraulic system?

100

An example of bernoulli's principle with a ping pong ball

The ping pong ball levitated when we blew fast moving air through a straw

200
The unit of pressure.
What is Pascal (Pa)?
200
The upward force that water and other molecules exert.
What is buoyant force?
200
It multiplies force by applying the force to a small area. The increase in pressure is then transmitted to another part of the confined fluid, which pushes on a larger surface area.
What is how a hydraulic system works?
200
As the speed of a moving fluid increases, the pressure within the fluid decreases.
What is Bernoulli's Principle?
300
A material that can easily flow and change shape such as air, water, oil or helium.
What is a fluid?
300

The mass per unit volume of a substance.

What is density?

300
It raises cars off the ground so mechanics can repair them with ease.
What is a hydraulic lift?
300
An upward force
What is lift?
400

Which one will create more pressure? 1 nail or 100 nails? 

1 nail 

400
mass/volume or mass divided by volume
What is the formula for density?
400
This part of a car multiplies force so a person can stop a large car with only a light tap.
What is a brake system?
400
In this device, the difference in pressure between the top and bottom of the tube draws the perfume upward.
What is an atomizer?
500
force/area or force divided by area
What is the formula for pressure?
500
The bouyant force acting on a submerged object is equal to the weight of the fluid the object displaces.
What is Archimedes' Principle?
500
When force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid.
What is Pascal's Principle?
500

Fast moving air has this kind of pressure.

What is low pressure?
