Energy
The energy associated with the motion AND position of an object
What is Mechanical?
No matter how energy is transferred, this is always given off.
What is Heat/Thermal Energy?
Mr. Cosby holds his hand over his computer which is overheating. He can feel the heat from a foot away!
What is Radiation?
The kinetic molecular theory states that everything is made of molecules and that those molecules are always ______.
What is Moving/In Motion?
The law of conservation of energy states that energy CANNOT be _______ ___ ________.
What is Created or Destroyed?
A toaster that is turned on.
What is Electrical to Thermal?
Mr. Cosby didn't know the toaster was on and picked it up. All the heat rushed to his hand and burnt it!
What is Conduction?
What happens to kinetic energy when you increase thermal energy.
What is it Increases?
Between being on top of a cliff vs being on the ground, this is where someone would have the MOST potential energy.
What is the top of a cliff?
The internal movement of particles.
What is Thermal?
A battery powering wires to turn a light on in a flashlight
What is Chemical to Electrical to Radiant?
Mr. Cosby goes swimming. The water feels warmer at the surface, but colder near the bottom of the pool.
What is Convection?
At 0 degrees Kelvin (or -273 degrees Celsius), this is the temperature at which all molecules stop moving.
What is Absolute Zero?
Energy is the ability to do what?
What is Work?
The type of potential energy that occurs when you press down a spring
What is Elastic?
A solar panel powering a motor in a toy car so it can move.
What is Radiant to Electrical to Mechanical?
Mr. Cosby likes using a wok to cook because the heat evenly distributes through all the metal to get good heat.
What is Conduction?
This is the temperature at which water boils in Celsius.
What is 100 degrees?
These three things affect potential energy
What are Mass, Gravity and Height?
When two atom nuclei combine together
What is Nuclear Fusion?
Plants turn the radiant and thermal energy from the sun into this kind of energy in the form of glucose.
What is Chemical Energy?
Mr. Cosby flies through the air on his hot air balloon which can fly because the fire it making hot air rise and fill up the balloon so the balloon can rise too.
What is Convection?
A solid will turn into this when thermal energy increases enough.
What is Liquid?
