light energy travels through _____________

light energy can move through _________________ empty space
Some light energy comes from the _________ sun
sound energy is the energy of _______________ in air, water, or other matter vibrations

thermal energy is due to randomly _______________ that make up matter

moving particles
thermal energy flow is felt as_________ heat
The faster particles move, the ________ thermal energy is produced more

potential energy is energy that is ____________ in an object

When an object is in motion, its potential energy is _____________ as other forms of energy released
Potential energy is released as other forms such as ____________,___________________, or _______________ sound, heat, or motion

kinetic energy is the energy of

A moving swing or a hurricane both have_____________ energy kinetic
All moving things have … kinetic energy.
The amount of kinetic energy depends on the _________ and __________ of the object. speed and mass
Gravitational, chemical, and elastic are all forms of ____________Energy Potential

A ____________ object has gravitational potential energy

The HIGHER or HEAVIER an object is, the more _________ _______________ __________ it has. gravitational potential energy

chemical is stored in the _____________ that hold particles together

The human body digests food and the chemical energy turns into other forms of energy used to ________,__________,and ______ move, talk, and live
a stretched rubber band or a compressed spring have ________ _________ _________ elastic potential energy
Elastic potential energy can change into ________ energy and _________ energy sound/kinetic
A Pendulum in a Clock: When a pendulum is at its highest position, it has the _________________. greatest potential energy
A Pendulum in a Clock: As the pendulum starts to swing down, the potential energy changes to __________ energy. kinetic
A Pendulum in a Clock: At its lowest position, the pendulum has the __________ kinetic energy. greatest
A Pendulum in a Clock: As the pendulum swings back up, the kinetic energy decreases and the potential energy___________. increases

Conduction is the transfer of

heat that occurs when one thing touches another.
Thermal energy flows from something warm to something cool.
Heat is the transfer of ______________ between matter of different temperatures. thermal energy
A heat source is anything that gives off energy that particles of matter can take in.

Convection is the transfer of

thermal energy as matter moves (as a gas or a liquid moves from place to place).
In convection, particles in warm air or liquid ______________________, while cooler air enters in to take the place of the warmer upward air or liquid move faster and travel upward

Radiation or radiant energy is energy that is sent out in

Radiant energy (radiation) is converted to thermal energy when it touches the matter of a person's body.
Radiation can travel through matter and through empty space.
Fossil Fuels come from the remains of organisms that lived millions of years ago
Coal, natural gas, and oil are all fossil fuels. When burned, fossil fuels produce useful heat.
Objects that are black absorb all the colors of visible light. When the light is absorbed, it becomes a form of heat.
