What is pressure?

"Pressure is equal to the force exerted on a surface divided by the total area over which the force is exerted." (Jones 75)

What is a fluid?

‚ÄčA fluid is a substance that flows. It can be a liquid or a gas.

What is fluid motion?

Fluid motion is simply when a fluid moves.

What makes a fluid flow?

A fluid flows when it moves from a place of high pressure to a place of low pressure. One example of how a fluids flow is when you take a sip from your drink through a straw you remove air from the straw which makes a place of low pressure in the straw. The high pressure in the straw pushes
down to the bottom of your drink which makes it come up through the straw.

What is Bernoulli's Principal?

"Bernoullis principal states that when the speed of a fluid increases the pressure decreases and when the speed of fluid decreases the pressure decreases."(Jones 96)

An example of Bernoulli's Principle is " Blowing air quickly between two cans it lowers the air pressure between them. Higher pressure exerted by the still air to either side pushes the cans toward each other." (Jones96)

Another example of Bernoulli's Principle is a curve in a baseball. This is because
in a stream of air (or other fluid) the pressure is inversely related to the speed, if the elevation does not change. As air moves faster its pressure drops. Giving the baseball it's movement to curve.

Another example of Bernoulli's principle is the way a car moves. A relationship between the elevation, pressure, and speed of a fluid. If there arent any changes in the hight, then as the speed of a fluid increases its pressure decreases. The faster a fluid is moving the lower its pressure, and the slower it is moving the higher its pressure. The fluid can be either a liquid or a gas. There are many examples of this effect, including some that we can observe while driving.
