Vocab
Any substance that can flow and take the shape of its container.
What is a fluid?
If an object floats, it means the weight of the fluid displaced and the buoyant force are this.
What is equal?
By making the output surface 4x larger than the input surface of a hydraulic press, when you put in 25N of force the output force becomes this.
What is 100N?
If a leaf enters a drainpipe and the pressure increases, the speed of the leaf will do this.
What is decrease?
Amount of forcer per unit area applied by a fluid.
What is pressure?
IF a diver displaces 400N of water, their buoyant force is this.
What is 400N?
Pascal's principle only applies to fluids in this kind of container.
What is closed?
When experiencing high winds outside, they will not affect the atmosphere inside until this happens.
What is the seal breaks?
OR
Is it the Doors/Windows open?
Something that describes the measure of the ratio of mass to volume.
What is Density?
A diver with a weight of 290N displaces 300N of water. This means his buoyant force is this.
What is 300N?
The input work and the output work when using Pascal's principle are always this.
What is equal?
This slows down an object moving through a fluid.
What is Drag Force?
The upward force applied by a fluid on an object inside the same fluid.
What is Buoyant Force?
This is the reason a hollow boat floats while one filled with water sinks.
Is it because the hollow boat is less dense than the water?
When pressure is applied to a fluid in a closed container, the pressure increases in this way.
Is it the same everywhere?
A soccer ball spins as it flies because of a difference in this.
What are wind pressures?
Ratio of the weight of all the air above your head to your surface area.
What is Atmospheric Pressure?
A volume of ice has less mass than the same volume of water, so this must be true.
What is ice floats?
To calculate the output force of a piston, we use the formula "F" = "P" * a where a is equal to this.
What is the area of the output force?
What is the density of a fluid?
