WJSH 8 Energy


energy the ability to cause change
kinetic energy energy of motion
potential energy stored energy
mechanical energy energy that moves objects
sound energy results from the vibration of particles in a solid, liquid or gas
chemical energy energy that is stored in the chemical composition of matter
thermal energy total amount of energy from the movement of particles in matter (causes heat)
electromagnetic energy energy transmitted through space in the form of electromagnetic waves (visible light, x-rays, microwaves)
nuclear energy energy from the center (nucleus) of an atom
law of conservation of energy energy cannot be created or destroyed
energy efficiency measurement of usable energy after an energy conversion
kinetic theory of matter all the particles that make up matter are always in motion
temperature measure of the average kinetic energy
thermal expansion solids, liquids, and gases expand when their temperature increases
heat flow of energy from an object at a warmer temperature to a cooler temperature
specific heat the amount of energy required to raise the temperature of 1 gram of a substance by 1 degree Celcius
conduction the process that moves energy from one object to another when they are touching physically
conductor material that transfers energy easily (metals)
insulator material that does NOT transfer heat easily (foam, plastic, wood, etc.)
convection the process by which cooler and denser air or liquid sinks, pushing the warmer up
radiation energy that travels as electromagnetic waves, which include visible light, microwaves, and infrared light (Sun is most significant source)
