Heat
The energy an object possesses due to its motion.
What is kinetic energy?
Slows down thermal energy transfer?
What is an insulator?
Lever, pulleys, inclined planes.
What are examples of simple machines?
These are used to change the direction of effort.
What are pulleys?
The measurement of a substance's ability to absorb or lose heat.
What is Specific heat capacity?
The random motion of particles suspended in a medium (a liquid or a gas).
What is Brownian motion
The cool air the travels over the water through convection.
What is sea breeze?
A lever where the fulcrum is between the effort and the load.
What is a first class lever?
W= F x d
What is the formula for work done?
The measure of how well and insulating material slows heat transfer
What is r-value?
The average kinetic energy of particles that make up a substance (clue: it's got to do with heat)
What is thermal energy?
The convection systems of warm, moist, unstable air along and ahead of cold fronts caused by severe thunderstorms.
What causes tornadoes?
A fishing pole is an example of this class.
What is third class lever?
The ratio of the output work a machine does with the input energy it uses to do that work.
What is efficiency?
Hammers, pliers, scissors are examples.
What is first class levers?
The transfer of heat by movement of particles.
What is convection?
These bodies of water moderate the climate in which they occur.
What are oceans?
A simple machine that easily moves a large load
What is force multiplier?
kW*h
the unit for amount of electricity (kW) used when in one hour (h).
Converts electrical energy to light and thermal energy.
What does a light bulb do?
The transfer of heat by electromagnetic waves
What is radiation?
Refrigeration, air conditioning, radiators on motor vehicles are examples.
What is heat transfer technology?
Wrench turning a nut is an example.
What is Wheel and axle?
Equilibrium
What is balance?
The object that is moved by a lever is called
What is the load?
