Final - Energy, Thermodynamics, Waves Flashcards
(16 cards)
Endothermic
Exothermic
Potential Energy
Stored energy
Nuclear Energy
Energy of the atom being split or fused
Electrical Energy
Energy of moving electrons
Radiant Energy -
Light energy - electromagnetic radiation
Gamma waves, x-rays, ultraviolet rays, visible light
Mechanical Energy
Energy (kinetic or potential) of moving objects or stored
ME = PE + KE
Chemical Energy
Energy of molecular bonds
Food, batteries, fuel
Thermal Energy
Heat - moving of molecules
Warm to cold - cold does not exist
Cooler objects molecules move less
Renewable Energy
Energy sources that can naturally replenish themselves quickly
Solar, Wind, Geothermal
Non-renewable resources
Sources of energy that run out before nature can replace them
Fossil Fuels - Oil, gas, coal, natural gas
Contributes to climate change
Kinetic Energy
What factors affect kinetic energy?
Energy of a moving object
1/2 x Mass x Velocity
Meteors, walking, falling, throwing a ball
Transverse Waves
Source of wave move up and down (perpendicular)
Light
Longitudinal Waves
Source of wave moves left to right (parallel)
Sound
Also called compressional waves
Electromagnetic Waves
Don’t require a medium
Examples: Light, microwaves, x-rays
