What is radiation?
Energy of moving electrons.
Electricity
What energy transfer is happening:
A fan plugged into the wall
electrical (plug) to mechanical (moving)
Stretched slingshot
Elastic Potential Energy
It happens when heat moves in waves through an area with no matter (eg. outer space).
What is radiation?
It happens when heat moves through air or liquid.
What is convection?
Energy that is stored in the bonds between elements
Chemical Energy
What energy transfer is happening:
