Elevation
Height above sea level
Is ice an example of a liquid?
No. To get full points name one liquid.
What force is constantly pushing on objects and people?
Gravitational forces.
What is Bernoulli's Principle?
Bernoulli's Principle states that as the speed of a fluid (like a liquid or gas) increases, the pressure within the fluid decreases.
In what year did Nintendo release the Game Cube? Hint between 2000-2010
2001
Define Pressure
Ratio of force to an area
What is different between gases and liquids?
Gases do not take up the same volume as a liquid.
Because the downward and upward pressure pushes on the diver along with buoyant forces that push the diver up.
What is Pascal's Principle?
Pressure is applied to a confined fluid, that pressure is transmitted equally in all directions throughout the fluid.
When was the song Buddy Holly by Weezer released? 1990-1999
1994
Define Fluid
A substance that can take the shape of the container that holds it or can flow.
What is similar between gases and liquids?
What is different between gases and liquids?
They both take the shape of the container they are in.
Gases do not take up the same volume as a liquid.
Describe how buoyant forces affect objects in the water/ air.
It makes the object feel lighter because the buoyant force pushes against the pressure pushing down.
How does an airplane wing use Bernoulli's Principle to generate lift?
The curved shape of an airplane wing causes air to flow faster over the top surface than the bottom surface. This faster airflow creates lower pressure above the wing, resulting in an upward force.
When did Creed release the song Higher? 1990-1999
1999
Define drag force
Is a force that can opposes the motion of an object through the fluid
Where are you more likely to feel atmospheric pressure? At the top of a mountain or 10 meters under the water? Why?
10 meters under the water. Because the atmospheric pressure isn't as much.
Define Archimedes' Principle.
The weight of a fluid that an object displaces is equal to the buoyant forces acting on an object.
How does a hydraulic jack use Pascal's Principle?
A hydraulic jack uses a small force applied to a small piston to create a much larger force on a larger piston. This is because the pressure applied to the fluid is transmitted equally throughout the system, resulting in a force amplification.
What type of pizza does Mr. Betts think is the best?
Hawaiian
Define Buoyant Force
An upward force applied by a fluid on an object in fluid
Where would the pressure come from if you were to put an object in a glass of water?
All around it.
Explain how Archimedes' Principle affects balloons filled with helium.
The helium is less dense than the air around it. Therefore it will rise. Over time the helium balloon will shrink and cause the gas inside the balloon to become more dense than the air around it. Gravity will bring it back to the surface.
How does the speed of an object affect drag force?
As the speed of an object increases, the drag force acting on it also increases.
When did Nintendo discontinued the Game Cube? Just in the United States. 2000-2010
2009
