Definitions
A system that uses pressurized air for a mechanical motion.
What is a pneumatic system?
X = length x width x height.
What is the formula for calculating volume?
A material that has no fixed shape and flows freely.
What is a fluid?
A diamond watch has a volume of 75ml and a mass of 300g. What is the density of the diamond watch?
Density = 4 cm3
An upward force that a fluid exerts on an object.
What is buoyancy?
The upward force a fluid exerts on an object.
What is buoyancy?
mass
X = ---------
Volume
What is the formula for calculating density?
This fluid has particles that are very spread apart and are able to move freely at high speeds.
What are gases?
There is 15 ml of juice in a cup and I add 5 ice cubes which cause the juice to rise to 20 ml. What is the volume of the ice cubes?
What is an example of displacement?
Anything that takes up space.
What is matter?
A ratio that compares mass to volume for a substance.
What is density?
If you known the density, you can use this formula to check your work
X = density x volume
What is the formula for calculating mass?
The explanation of why matter behaves the way it does.
What is Particle Theory?
This system is heavy and filled with liquid. It is used in syringes.
What is a hydraulic system?
If pressure is exerted on a fluid, it will be evenly distributed throughout the fluid.
What is Pascal's law?
The measure of a fluids resistance to flow.
What is viscosity?
This formula is an important component in the fluid’s unit
Force
X = --------
Area
What is the formula for calculating pressure?
Adding heat makes particles move faster.
What is one of the major points of particle theory?
This vehicle uses ballast tanks that take in water when they need to sink. And use compressed air to remove water when needed to float.
What are submarines?
?=Force normal to a surface
---------------------
Area of surface
What is the formula for calculating pressure?
A measure of how strongly fluid particles are attracted to each other.
What is cohesion?
X = 478.5 x 39 cm3
What is the mass of 18661.5g
This factor affects the viscosity of a fluid.It is the resistance a surface has when it rubs against another.
What is friction?
You have been asked to clean up an oil spill. Your boss tell you to use a chemical agent to solidify spilled oil, making it easier to collect. What method is he talking about?
What are gelling agents?
The attraction between the particles of a fluid and another substance.
What is Adhesion?
