Transfer of energy by electromagnetic waves


Transfer of energy by electromagnetic
waves

Heat moving in the form of waves

Example: Sun heating Earth’s surface



Transfer of heat between particles within
a substance
Heat moving between 2 items touching
always hot  cold
Examples
◦ Pan on a hot stove
◦ Feet on hot beach

Transfer of heat by the movement of
currents

Hot up, cold down

Examples
◦ Magma in mantle
◦ Convection currents

The potential energy stored in the nucleus of
an atom

Must split atom to get energy

Examples
◦ Nuclear power plants
◦ Atomic bombs

The energy produced by an object’s
vibrations

If you hear it, it has sound energy

Examples
◦ Music
◦ Cars


Kinetic or potential energy associated
with the motion or position of an object
Examples
◦ Bicycle
◦ Pencil sharpener
◦ Blender

Energy of light

Example: Light Bulb

Energy of moving electrical charges

Electricity
◦ Flow of electrons or negative charges

Example: Anything that has wires or
plugs in


Potential energy stored in chemical
bonds
Examples:
◦ Inside of batteries
◦ Tip of match

Total energy of particles in an object

Heat energy
Temperature

Example: Fire


Rule that energy can not be created or
destroyed
◦ Can be transferred



Energy that is stored
Depends on height
The higher an object, the more PE it has


Energy that an object has due to its
motion
Depends on mass and speed
◦ Faster = more KE
◦ Heavier = more KE

On notebook paper, list 5 things/items that
have energy.
For each thing, list all the types of energy that
that thing has.
