This is a substance that can change shape
Fluid
This is obtained when density is multiplied by the volume occupied by an object
mass
state the type of fluid used in a hydraulic system
liquid
What force exerted by the body changes depending on what planet you are on?
Force of Gravity
A substance with a mass of 12g and density of 6g/ml has this volume
2 ml
This is the SI unit of pressure and Force
Pascal (Pa)
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.
Buoyant force
This type of force does not cause a change in motion of an object
balanced force
What measurement stays the same, even if you were to go to the surface of a smaller or bigger planet?
Mass
what is the density of a 2.5 cm3 glass marble that has a mass of 7.5 g?
3
What happens to pressure as surface area decreases
Increases
According to ........ principle the buoyant force on an object is equal to ......... displaced by the object
the Archimedes' principle
the weight of the fluid displaced
When you are trying to get the last bit of toothpaste of of the tube, what principle do you apply to get it out?
Pascal's Principle
What is the relationship between viscosity and flow rate?
As one goes up, the other goes down.
what is the volume of 20 g of a liquid with density equals 1g/ml
20 ml
These are the two units for volume measurement
mL and cm3
This is how you can predict whether an object will float or sink in a fluid
Density
A car lift in a garage is an example of what type of system?
hydraulic systems
What 3 factors effect the viscosity of a substance?
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. From this information calculate the density of iron.
7g/ml
This is a type of force that causes a change in motion of an object
Unbalanced force
How to metal ships float in water?
Average density, air much less dense
What type of fluid is used in a pneumatic system?
Gas
This factor must stay the same during an experiment
Controlled variable.
What volume of silver metal will weighs exactly 2500.0 g. The density of silver is 10.5 g/cm3.
