Pressure
This is a substance that can change shape
What is a Fluid?
This is obtained when density is multiplied by the volume occupied by an object
What is mass?
This type of fluid is used in a hydraulic system
What is a liquid?
This is the force exerted by the body changes depending on what planet you are on.
What is the Force of Gravity?
A substance with a mass of 12g and density of 6g/ml has this volume
What is 2 ml?
This is the SI unit of pressure and Force
What are Pascal (Pa)
and
Newtons (N)?
This is the force that acts opposite the force of gravity and makes an object feel lighter. It pushes up on an object.
What are Buoyant forces
This type of force does not cause a change in motion of an object
What is a balanced force?
This measurement stays the same, even if you were to go to the surface of a smaller or bigger planet.
What is Mass?
The density of a 2.5 cm3 glass marble that has a mass of 7.5 g.
What is 3?
This is what happens to pressure as surface area decreases
What is pressure Increases?
According to ........ principle the buoyant force on an object is equal to ......... displaced by the object
What is Archimedes' principle
and
the weight of the fluid displaced?
When you are trying to get the last bit of toothpaste of of the tube, this is the principle you apply to get it out.
What is Pascal's Principle?
This is the relationship between viscosity and flow rate?
What is As one goes up, the other goes down?
This is the volume of 20 g of a liquid with density equal to 1g/ml
What is 20 ml?
These are the two units for volume measurement
What are mL and cm3 ?
This is how you can predict whether an object will float or sink in a fluid
What is knowing whether the object is more or less dense than the fluid?
A car lift in a garage is an example of what this type of system.
What is a hydraulic system?
These 3 factors affect the viscosity of a substance.
What are Temperature, concentration, attractive force?
28 g of iron is added to graduated cylinder containing 45 ml of water. The water level rises to the 49 ml mark. This is the density of iron.
What is 7g/ml?
This is a type of force that causes a change in motion of an object
What are Unbalanced forces?
This is why metal ships float in water?
What is a lower Average density? air much less dense
This type of fluid is used in a pneumatic system?
What is a Gas?
These factors must stay the same during an experiment
What are Controlled variables?
This volume of silver metal weighs exactly 2500.0 g. The density of silver is 10.5 g/cm3.
What is 238.09 gm3 ?
