Turbine
A wheel of curved blades that spins a driveshaft; changes the force exerted by things such as wind or pressurized gases into Ratary motion
Matter
Anything that takes up space and has mass
Combustion
Burning
Fluid
Concert info from one place to another such as a liquid or gas
Chemical energy
Energy that is stored in the Bonds to hold molecules and chemical compounds together
Octane number
I number indicating the antiknock of quality of a gasoline
Lodestones
Pieces of naturally magnetized Iron ore
Potential energy
Stored energy
Engine
Such devices that can convert energy from natural sources into useful work
Energy
The ability to do work
Kinetic energy
The energy of motion
Gravity
The force of attraction that exists between any pair of objects
Friction
The force that resists motion
Condenser
The place for the old steam goes where it is cooled and change back into water
wind mills
What Devices have been developed to harness wind power?
Oxygen rich compounds
What are oxidants?
A water wheel
What device was developed to harness the power of moving water?
The contract
What happens when like poles or charges are brought close together
They attract
What happens when opposite poles or charges are brought close together?
propellant
What is produced when oxidants and chemical fuels are mixed together?
212°F and 100°C
What is the boiling and condensation point of water?
32°F and 0°C
What is the melting and freezing point of water?
liquid fuel rocket
What is the other type of rocket?
Condensation Point
What is the temperature at which a gas changes into a liquid? What is that called?
Boiling point
What is the temperature at which a liquid changes into a gas? What is that called?
Freezing point
What is the temperature at which a liquid changes into a solid? What is that called?
Melting point
What is the temperature at which a solid changes into a liquid? What is that called?
Defusion
What is the tendency of gases to spread themselves out thinly
Transfer of energy
When one object gives some or all of its energy to another object
Gases and liquids
Which states of matter have no permanent shape?
The rocket
Which type of engine carries its own supply of oxygen?
The steam engine
Which type of internal combustion engine produces no spark?
solid fuel rocket
Which type of rocket uses propellants?
Because ice has little holes in it to let air in and water does not have the little holes to let air in
Why is ice lighter than liquid water?
Missile
a guided military rocket
Payload
the cargo that is carried in the nose of a rocket
Work
A result of a force moving an object
Piston
A disc that moves back-and-forth inside a hollow cylinder
Contact force
A force that occurs when one object pushes against another object
Cylinder
A hollow cylinder shaped compartment in which a piston moves back and forth in an engine
Ramjet
A jet engine that can function only at high speed because it has no turbine
Turboprop
A jet engine used to power a propeller
Turbofan
A jet engine with a large fan at the very front
A. Force
A push or a pull
