Heat Energy Transfer
What is the study of thermodynamics?
The study of how heat moves
Energy used by movement is called:
Kinetic energy
What are the two main types of Energy?
Kinetic and potential energy
Energy is measure in
Joules
Moving
Kinetic energy
What are three ways that heat is transferred?
Conduction, convection and radiation.
Energy that is stored in objects is called:
Potential Energy
If an object is moving slowly it has _______ kinetic energy
Low
An electric fan transforms ________ energy into _______ energy
Electrical energy, kinetic energy

What is waste energy?
When energy is produced but not used, or when it is used inefficiently
Energy in a person on top of a slide
Gravitational potential energy
The cyclical flow of heat through air or liquid.
Convection
_________ energy is produced by vibrating objects
Sound
Energy stored in objects due to their height above the ground.
