Thermal Energy

Kinetic Energy Moving energy

Potential Energy Stored Energy

Thermal Energy The total potential and kinetic energy of the particles in an object (more kinetic energy of particles= more heat, less kinetic energy of particles= less heat)

Radiation Transfer of thermal energy by electromagnetic waves through places with or without matter (examples: light bulb, campfire, fireplace, microwave, Sunlight)

Convection Transfer of thermal energy by liquids or gases (Examples: cup of soup, boiling water, hot air balloon)

Convection Current A continual cycle of heat rising, cooling, sinking, and moving to replace rising heat (example: gulf stream, El Nino/ La Nina, jet stream)

Conduction Transger of thermal energy between things that are touching (examples: electrical circuit, ice in water, insulation inside walls)

Conductor Matter through which energy flows easily (a metal pot was a good conductor of heat)

Insulator Matter thorught which energy does not flow easily (the cooking mitt insulating a hand)

Equilibrium (heat) The balance between heat loss and heat gain (the hot bathwater cooling to room temperature)

Greenhouse Effect The heating effect of the Earth’s atmosphere; the atmosphere acts like a greenhouse because sunlight freely passes through it and warms the surface, but the earth’s re-radiated heat is slowed in its escape from the planet back to space.
