Thermal EnergyChemical EnergyElectrical EnergyRadiantNuclearMechanical

Energy created from the movement of molecules (kinetic energy) The faster the particles move the

greater the energy and the greater the objects thermal energy▪ Example: Steam Engine

▪Energy created as the atoms of a substance are rearranged through a chemical reaction.▪Can be a form of potential energy

depending on the position and atomic arrangement▪Example: Batteries Wet /Chemical Cell/ or Dry Cell

Energy created through the movement/flow of electrons. (current) ▪Measured in volts and amperes▪Example: Electricity

Energy that radiates out from a source.▪ Is considered a form of kinetic energy▪ Produced by vibrations of electrically

charged particles coming from a source (sun. lights, heater) that travels in waves called transverse wavesExample: Sunlight (Electromagnetic Radiation)

Energy created from the combining of the nuclei or splitting of the nucleus of an atom:▪Two types▪Fusion (Combining)▪Fission (Splitting)

◦ The Energy of/in motion ◦ Can be classified as either potential

or kinetic depending on the circumstances. ◦ If its moving, then it is mechanical

energy!

◦When an object is at rest it has potential mechanical energy◦ Ball at top of ramp (Potential)◦ When an object is in motion it has

kinetic mechanical energy. ◦ Car moving down the road (Kinetic)

Get together with your lab partner and go to the workstation that corresponds with your table number.

Follow the directions for the lab beginning on page 2.

Complete Page 2 Go to your seats to complete page 3 If you complete page 3, read page 4 and begin

to research Nuclear Energy in your textbooks and begin page 5.

Energy is the ability to do work or create change

There are 2 major categories of energy Potential Energy – Stored Energy▪Ex. Batteries, Tank of gas

Kinetic Energy – Energy in Motion▪EX. Car Moving, Bowling Ball Rolling

There are 6 basic forms of energy Radiant Thermal Chemical Electrical Mechanical Nuclear

An energy chain is a tool used to describe how energy changes as it moves along the line

It identifies each type of energy as it transforms from one form to another

Energy SourceA term used to identify where the

energy chain begins or where the energy comes from

Energy ReceiverA term used to identify where the

energy chain ends. In many cases YOU are the

receiver

As energy transforms from one form to another, some of the energy is lost as heat, but energy is never created or destroyed under ordinary circumstances

This is called The Law of Conservation of Energy

Nuclear Energy Two types▪ Fission : ▪Splitting the nucleus of an atom▪We can perform fission on earth

▪ Fusion: ▪Combining the nuclei of two or more atoms▪Done in the Sun
