Density
The equation for density.
What is D = m/V?
Buoyancy always acts in this direction.
What is up?
The equation for pressure.
What is P = F/A?
This is the same for 10 ml of water and 10 ml of oil.
What is volume?
The density of a 200 gm rock with a volume of 100 cm3.
What is 2 g/cm3?
The density of an object determines whether or not it will do this in water.
What is float or sink?
This is how the buoyant force of a 10 cm3 object weighing 50 N compares to the buoyant force of a 10 cm3 object weighing 25 N.
What is the same?
The unit of pressure.
What is the pascal?
The physical property that determines whether or not an object will float.
What is density?
The pressure when a 500 N force is exerted over a 2 m2 area.
What is 250 pascals?
This is how the density of a whole candy bar compares to the density of a half of the candy bar.
What is the same?
Liquids and gases both are considered to be this.
What is fluids?
This is the direction that pressure is exerted on an object in the water by the water.
What is all directions?
This force remains constant no matter how deep an object goes under water.
What is buoyant force?
The volume of a rectangular prism measuring 5 cm by 10 cm by 2 cm.
What is 100 cm3?
The common units of density.
What is g/cm3?
"The buoyant force of an object is equal to the weight of the fluid displaced."
What is Archimedes' principle?
This is how the pressure at the bottom of a swimming pool compares to the pressure near the surface.
What is greater?
This is how the space between atoms in a very dense object compare to the space between atoms in a less dense object.
What is less or smaller?
The density of an oil under these conditions. An empty beaker with a mass of 25 grams is filled with 100 cm3 of the oil. It now as a total mass of 75 grams.
What is 0.5 g/cm3?
The density of water.
What is 1 g/cm3?
This is how the net force on top of an object compares to the net force on the bottom of the object.
What is less?
1 atmosphere = this many mm Hg.
What is 760?
This is used to measure the volume of a liquid.
What is a graduated cylinder?
A rock with a mass of 50 grams and a volume of 80 cm3 will do this when placed in water.
What is float?
